Synthesis of Au-assisted GaAs Nanowires on Si Substrate by Pulsed-jet Epitaxy Method

GaAs nanowires (NWs) assisted Au catalyst on the Si (111) substrate have been synthesized by employing the pulsed-jet epitaxy method. The effect of growth conditions was evaluated by changing the formation and the growth direction of the NWs. Increasing the Au droplet diameter, the number density of NWs reduced and the length of NWs became longer. In the higher growth temperature, the distribution of the growth direction on the nanowire axis was small, and the NWs grow to perpendicular direction to a substrate. However, the desorption of As restrain the growth of NWs more than 550 ℃.departmental bulletin pape

Solar neutrino measurements in Super-Kamiokande-II

The results of the second phase of the Super-Kamiokande solar neutrino measurement are presented and compared to the first phase. The solar neutrino flux spectrum and time variation as well as oscillation results are statistically consistent with the first phase and do not show spectral distortion. The timedependent flux measurement of the combined first and second phases coincides with the full period of solar cycle 23 and shows no correlation with solar activity. The measured 8B total flux is (2:38± 0.05(stat.)/begin+0.16 // -0.15/end (sys.)) × 10^6 cm^{-2} s^{-1} and the day-night difference is found to be (-6.3 ±4.2(stat.)±3.7(sys.))%.There is no evidence of systematic tendencies between the first and second phases.journal articl
