STM Observation of Au Particles Adsorbed on Si(111)-Clean Surface by PLD Method

To obtain important information for fabricating atomic-scale Au thin films that are used for biosensors, we have examined the flushing temperature for forming the Si(111) clean surface and observed the morphology of Au particles adsorbed by Pulsed Laser Deposition method on a Si(111)-7×7 surface by STM, which is supposed to be the initial stage of Au atomistic thin film formation. As the result of this study, it was found that flushing temperature must be controlled within 5℃ and we can fix the flushing requirement by STM images. Besides, we have estimated that Au particles are adsorbed on the position which is about 0.21 ± 0.03 nm away from the center of Si adatom.departmental bulletin pape

Development of Focusing and Irradiating System for Laser-stimulated Desorption Spectrometer

Vacuum ultraviolet (VUV) with a wavelength of 100-200 nm has a photon energy of about 6-12 eV, which is higher than the binding energy of many substances, and has the feature of being able to break chemical bonds. We have applied these features to develop an analyzer named the Photon-stimulated Desorption Spectrometer. Since the spatial and temporal resolutions of this system are low due to adaption of incoherent light source, it is expected to improve by replacing the light source with an ultrashort pulsed VUV laser. In the present study, we have developed a focusing and irradiating system that enables various laser irradiation modes by overlapping multiple beams spatially and temporally. High-precision position control of the focusing and irradiating system is necessary for this purpose. Here, we used a number of micrometers with encoder that can be computercontrolled with a resolution of 1 μm to develop a double beam focusing and irradiating system using currently available ultrashort pulsed lasers with wavelengths of 800 nm and 400 nm. As a results, we confirmed that the smaller spot diameter was obtained by using the shorter wavelength. The spatial superposition can be performed within an accuracy range of ±3 μm, and the temporal superposition can be performed with an accuracy of 33 fs. Besides, interference fringes were obtained by angled irradiation of two light beams which can be expected to induce desorption in finer areas.departmental bulletin pape
