Electronic structure and tunneling resonance spectra of nanoscopic aluminum islands

The electronic structure of nanoscopic oxide-coated aluminum islands is investigated using a tight-binding model that incorporates the geometry, chemistry and disorder of the particle. The oxide coat is found to significantly increase the volume accessible to electrons at the Fermi level. The level statistics agree with random matrix theory predictions. States near the Fermi level show pronounced clustering regardless of disorder. It is suggested that the observed clusters of tunneling resonances may have a more complex origin than if they were solely due to many-body non-equilibrium effects.Comment: To be published in Phys.

Precision measurement of magnetic characteristics of an article with nullification of external magnetic fields

An apparatus for characterizing the magnetic field of a device under test is discussed. The apparatus is comprised of five separate devices: (1) a device for nullifying the ambient magnetic fields in a test environment area with a constant applied magnetic field; (2) a device for rotating the device under test in the test environment area; (3) a device for sensing the magnetic field (to obtain a profile of the magnetic field) at a sensor location which is along the circumference of rotation; (4) a memory for storing the profiles; and (5) a processor coupled to the memory for characterizing the magnetic field of the device from the magnetic field profiles thus obtained

Dependence of the electronic structure of self-assembled InGaAs/GaAs quantum dots on height and composition

While electronic and spectroscopic properties of self-assembled In_{1-x}Ga_{x}As/GaAs dots depend on their shape, height and alloy compositions, these characteristics are often not known accurately from experiment. This creates a difficulty in comparing measured electronic and spectroscopic properties with calculated ones. Since simplified theoretical models (effective mass, k.p, parabolic models) do not fully convey the effects of shape, size and composition on the electronic and spectroscopic properties, we offer to bridge the gap by providing accurately calculated results as a function of the dot height and composition. Prominent results are the following. (i) Regardless of height and composition, the electron levels form shells of nearly degenerate states. In contrast, the hole levels form shells only in flat dots and near the highest hole level (HOMO). (ii) In alloy dots, the electrons' ``s-p'' splitting depends weakly on height, while the ``p-p'' splitting depends non-monotonically. In non-alloyed InAs/GaAs dots, both these splittings depend weakly on height. For holes in alloy dots, the ``s-p'' splitting decreases with increasing height, whereas the ``p-p'' splitting remains nearly unchaged. Shallow, non-alloyed dots have a ``s-p'' splitting of nearly the same magnitude, whereas the ``p-p'' splitting is larger. (iii) As height increases, the ``s'' and ``p'' character of the wavefunction of the HOMO becomes mixed, and so does the heavy- and light-hole character. (iv) In alloy dots, low-lying hole states are localized inside the dot. Remarkably, in non-alloyed InAs/GaAs dots these states become localized at the interface as height increases. This localization is driven by the biaxial strain present in the nanostructure.Comment: 14 pages, 12 figure

First palynologic record of the Cretaceous La Yesera Formation (Salta Group), northwestern Argentina

Thirty-four taxa were documented from six palynologically productive samples of the La Yesera Formation (Brealito and Don Bartolo Members) in the Pucará locality (Salta Province, northwestern Argentina). In the Brealito Member, aquatic species (mainly freshwater algae) dominate the palynofl ora, while terrestrial species are represented by trilete spores (mainly Anemiaceae) and gymnosperm pollen grains. In the Don Bartolo Member, Classopollis spp. dominate most of the assemblages, trilete Anemiaceae spores constitute half of the total counts in one of the assemblages and a unique angiosperm species (Tricolpites variabilis) was found in two assemblages. Ephedra-type pollen grains (three genera and six species) appear in both members, although in low abundance. The results support previous sedimentology studies that indicate a perennial lake environment at the time of deposition of the Brealito Member, with evidence for dry seasonality in the Don Bartolo Member. The inferred regional paleoclimate is subtropical with arid conditions. Considering the stratigraphic ranges of selected species and the sedimentology data, an Albian/Cenomanian age is suggested for the unit.Trinta e quatro táxons foram registrados a partir de seis amostras palinológicas provenientes da Formação La Yesera (membros Brealito e Don Bartolo), na localidade Pucará, Província de Salta, noroeste da Argentina. No Membro Brealito, predominam as espécies aquáticas, principalmente de algas de água doce; as espécies terrestres estão representadas por esporos triletes, principalmente de Anemiaceae e por grãos de pólen de gimnospermas. No Membro Don Bartolo, os grãos de pólen Classopollis spp. dominam a maioria das assembleias, embora numa das amostras, metade das contagens totais é constituída por esporos triletes de Anemiaceae e, uma única espécie de angiospermas (Tricolpites variabilis) foi encontrada em duas assembleias. Grãos de pólen do tipo Ephedra, com três gêneros e seis espécies, aparecem em baixa abundância em ambos os membros. Estes resultados corroboram estudos sedimentológicos anteriores e indicam ambiente lacustre perene, no momento da deposição do Membro Brealito, com evidência de sazonalidade seca para a Membro Don Bartolo. O paleoclima regional inferido é subtropical árido. Considerando os intervalos estratigráfi cos de espécies selecionadas e os dados sedimentológicos, é sugerida idade Albiano/Cenomaniano para a unidade estudada.Fil: Narvaez, Paula Liliana.

Ajuste de cono con ajuste de agua: cambios en la razón agua/cemento, que alteran las resistencias de un hormigón premezclado

Tesis (Ingeniero Constructor)En el proceso industrializado de producción de un hormigón, llamado Hormigón Premezclado (H.P.), existen múltiples variables que alteran los resultados finales de éste o mejor dicho, que afectan las resistencias de un hormigón. La importancia de ir disminuyendo la variabilidad de resultados de un H.P., se ve reflejado tanto para bajar costos de producción hasta implicancias medio ambientales en la disminución de utilización de recursos que impactan nuestro sistema. Las variables pueden estar en diferentes etapas del proceso de producción, es por eso que la presente investigación se enfocará en un punto específico del proceso, el cual es “Ajuste de Cono en Planta” localizado en la etapa de mezclado de producción de una planta de H.P. Para llevar a cabo esta investigación se plantea un trabajo en terreno, en una planta de hormigones premezclados, con una serie de tareas tales como; mediciones de tiempo y cantidad de adición de agua, resistencias a la compresión. Con el fin de abordar puntos como la baja de resistencias de los hormigones y variabilidad entre estos, necesarios para determinar los aspectos relevantes en proceso de ajuste de cono en planta. Como resultado de la investigación se presenta una propuesta de trabajo para el puente de ajuste de cono (instructivo de trabajo), con el fin regular la participación de los operadores mixer y las razones agua / cemento dentro de parámetros que disminuyan la variabilidad de las resistencias.Within the industrialized process of concrete productions, also called Premix-Concrete (P.C), there are a series of variables that may affect the final outcomes of it or that affect the resistance of concrete itself. The importance of decreasing the board possibilities of outcomes of a P.C is reflected both in lower production costs and the environmental implications in reducing the use of resources that may impact our eco-system. Such variables can be found in different stages of the production process, that is why this piece of research aims to an specific area in the process, which is called “Adjusting Cone Plant”. That it is located in the mixing stage production of a P.C plant. To develop this investigation, a field work in an premixed concrete plan is proposed, with a serie of tasks such as: time measurement and the amount of water that is added throughout the process, and compressive strengths are also considered as relevant for the purpose of this investigation. The aim of this is to address issues Such as low resistance of concrete and the variability among them which are necessaries to determine the relevant aspects in the process of adjusting the cone plant. As a result of this research, a work proposal is presented in order to tackle the issues that may occur in the bridge adjusting cone (instructive of work), with the main aim of regulating the participation of mixer operators and the amount of water and cement used on the process within the parameters that could reduce the variability of concrete resistance

Nominally forbidden transitions in the interband optical spectrum of quantum dots

We calculate the excitonic optical absorption spectra of (In,Ga)As/GaAs self-assembled quantum dots by adopting an atomistic pseudopotential approach to the single-particle problem followed by a configuration-interaction approach to the many-body problem. We find three types of allowed transitions that would be naively expected to be forbidden. (i) Transitions that are parity forbidden in simple effective mass models with infinite confining wells (e.g. 1S-2S, 1P-2P) but are possible by finite band-offsets and orbital-mixing effects; (ii) light-hole--to--conduction transitions, enabled by the confinement of light-hole states; and (iii) transitions that show and enhanced intensity due to electron-hole configuration mixing with allowed transitions. We compare these predictions with results of 8-band k.p calculations as well as recent spectroscopic data. Transitions in (i) and (ii) explain recently observed satellites of the allowed P-P transitions.Comment: Version published in Phys. Rev.

Machinability Study of an aluminum-copper alloy

Machinability of materials is one of the factors that make us wonder what tools to use and what material is best suited for a particular cutting tool and which process is more efficient in the production of a component. In the case of parts for the aerospace industry, manufacturing processes assume greater importance due to the extreme demands on reliability and quality
