Abstract

We study the photomission from ternary and quanternary alloys systems by formulating the respective expressions considering the spin & broadening of Landau levels. It is found taking n-Hg1−x CdxTe and In1−xGaxAsyP1−y lattice matched to InP as examples of ternary and quaternary alloys respectively that the photoemission exhibits oscillatory magnetic field dependence and increases with increasing electron concentration in spiky manner for both the cases. The numerical magnitudes of photoemission in ternary alloys are greater than that of the quaternary systems and the theoretical formulations are in agreement with the experimental observations as reported elsewhere.
