Profile | My specialty is the basic physical properties of semiconductors such as group III V materials and group IV materials, and the interface physical properties between semiconductor materials and dissimilar materials (metals and insulating materials). The main analytical method is X-ray photoelectron spectroscopy (XPS), which can evaluate the composition, chemical bond state, and electronic state of thin films. We are researching semiconductor devices by evaluating the physical properties of various materials using XPS and the bonding state of surfaces and interfaces. Recent research themes include evaluation of ferroelectric semiconductor materials such as AlScN, which are expected to be applied to non-volatile memory, elucidation of the interfacial dipole mechanism, evaluation of TiO2 and Al2O3 deposited on semiconductors by atomic layer deposition, and solar cells. We are conducting research such as evaluation of protective films and carrier transport layers, and elucidation of the initial process of SiC oxidation. I have an angle-resolved photoelectron spectrum analysis system that can evaluate the composition and chemical bond state of thin films with a depth resolution of nm or less, which I have created based on my own research so far. |
