Dynamics of Hot Electrons “Accumulated” in the Velocity Space of CdS with Acoustic Phonon Interactions

抄録

Transport phenomena of photoexcited electrons in CdS have been investigated at crossed electric and magnetic fields. Dynamics of electrons at the so-called “accumulation” area in the velocity space, escaping from the LO-phonon emission, has been clarified in a view of the hot electron effect at strong transverse magnetic fields, particularly in the case of interaction with acoustic phonons, both the deformation-potential coupling and piezoelectric coupling included.
