Paper Abstract

The Faraday rotation is a sensitive method for determining the effective mass ot the charge carriers in a two-dimensional (20) electron gas. One of the most important techniques in studying surfaces and interfaces of silicon is the metal-oxide-semiconductor (MOS) technique. The electric field applied between the metal layer and the silicon results in a quantization of the charge distribution. The resonance effective mass, the scattering parameters, and the populations of the subbands may be determined at light frequencies close or equal to the cyclotron frequency. The technique could also be applied to study other semiconductors. In III-V compound semiconductors and narrow-gap semiconductors the effective mass is much smaller than in silicon. Since the tree carrier Faraday rotation is inversely proportional to the effective mass squared, the 21) Faraday rotation should be easily observable in these semiconductors.
