OPTICAL PROBING OF LOCALIZED ELECTRONhyphen;HOLE PLASMAS INnhyphen;TYPE InSb

摘要

A CO2laser is used as a hole density probe in order to study lowhyphen;field contact effects innhyphen;type InSb near liquidhyphen;nitrogen temperaturemdash;injection at the anode and avalanche, in presence of a transverse magnetic field, and at the cathode. These two effects are shown to be present during acoustoelectric oscillations.
