摘要

Raman scattering studies have been recently used to relate the strain in the semiconductor layer structure w ith the line shape of allowed moes. It can yield important information about the nature of the solid on a scale of the order of a new lattice constants. It can also provide an evaluation on the carrier concentration in the channel layer of high electron mobility transistors (HEMTs). In this investigation, Raman scattering was used to study the effect of varying the In mole fraction (x) from 0.53 to 0.81 in the In_xGa_(1-x)As channel layer of InGaAs/InP heterostructures. The effect of varying the doping concentration in the donor layer from 6x10~(17)/cm~3 to 2.5x10~(18)/cm~3, and the effect of varying the In_(0.75)Ga_(0.25)As channel thickness from 140 A to 260 A are also reported.
