Determination of the electron trap level in Fe-doped GaN by phonon-assisted conduction phenomenon
Hiroki Fukuda, Akira Nagakubo, Shigeyoshi Usami +6
We acoustically measured the energy level for thermally activated conduction (TAC) in high-resistivity Fe-doped GaN using the non-contacting antenna-transmission acoustic-resonance…

Interplanar stiffness in defect-free monocrystalline graphite
Koichi Kusakabe, Atsuki Wake, Akira Nagakubo +4
The interplanar bond strength in graphite has been identified to be very low owing to the contribution of the van der Waals interaction. However, in this study, we use microscopic…
