Outline of Final Research Achievements

In many electric devices, the behavior of electron in conduction band defines the performance of the devices. Therefore, the evaluation of conduction band structure is critical to design electrical devices. In this study, we evaluated the conduction band structure by using visible-light photoelectron spectroscopy developed by our group. In particular, we developed how to evaluate the wavenumber information. We successfully developed the method of determination of wavenumbers and we applied this method to evaluate the GaN conduction band.
In addition, we evaluated the band structure of conduction mini-band in semiconductor superlattice.
