Interaction of 10.6 um Radiation with Current Carriers in Germanium.
Abstract
The absorption of 10.6 micrometer energy by excess carriers in germanium is used to study carrier profiles within the bulk of intrinsic material. Excess carriers are injected into blocks of germanium with dimensions in the millimeter range. The material is probed by a fine beam from a CO2 laser and the energy in the exit ray is measured to determine carrier absorption. Carrier density in the material is found to correspond to two distinct patterns. The absence of space charge and pronounced carrier recombination was noted. The determination of carrier cross section is discussed. (Author)
