[LSC6-03(Invited)] Electronic coherence time in n-type gallium arsenide

*Kazutaka Nakamura1, Yosuke Kayanuma2, Itsuki Takagi1 (1. Tokyo Institute of Technology, 2. Osaka Metropolitan University )

Electronic coherence time in n-type gallium arsenide is determined by using ultrafast quantum-path interferometry with quantum mechanical calculations. Its temperature dependence is discussed in terms of electron interaction with carriers, phonons and impurities.
