Direct Determination of Exciton Wave Function Amplitudes by the Momentum-Resolved Photo-Electron Emission Experiment
Hiromasa Ohnishi, Norikazu Tomita, Keiichiro Nasu
We study conceptional problems of a photo-electron emission (PEE) process from a free exciton in insulating crystals. In this PEE process, only the electron constituting the excito…

Instantaneous Intervalley Transition just at the Franck-Condon State in the Conduction Band of GaAs
Hiromasa Ohnishi, Norikazu Tomita, Keiichiro Nasu
We propose two possible quantum microscopic mechanisms for intervalley transitions just at the Franck-Condon state in GaAs. The first is the simultaneously combined coulombic elast…
