Microwave-modulated photoluminescence: technique and application to III-Vs (Poster Paper)

A new modulation spectroscopy, microwave modulated photoluminescence (MMPL), is described. Application of the technique to a well characterized semiconductor system, InP:Zn, in which the radiative recombination processes are not understood, allows interpretation of the resulting spectra. In the ordered ternary Ga 0.52 In 0.48 P MMPL provides information about both carrier transport properties and the extent of ordering. When applied to new materials, MMPL can aid identifying radiative recombination processes.
