Investigation of Laser Optical Biasing on the Quantum Transport Properties of n-InSb.

Abstract

The interaction of CO2 and CO laser radiation with the semiconductor InSb has been studied at liquid helium temperatures with a highly sensitive photoconductive technique. Two distinct sets of resonant magnetophotoconductivity structure have been observed and identified as arising from multiphonon assisted cyclotron harmonic transitions and impurity level transitions. The first observation of a laser induced cooling process of the conduction electrons in n-InSb has been made using a CO laser and an applied dc electric field. (Author)
