Semiconductors solid solutions

Solid-Solution Models. Compared with the liquid phase, very few direct experimental determinations of the thermochemical properties of compound-semiconductor solid solutions have been reported. Rather, procedures for calculating phase diagrams have relied on two methods for estimating solid-solution model parameters. The first method uses semiem-pirical relationships to describe the enthalpy of mixing on the basis of the known physical properties of the binary compounds (202,203). This approach does not provide an estimate for the excess entropy of mixing and thus...

It is known that far-infrared (FIR) spectra give direct information on phonon modes and impurity levels in the crystal lattices. Infrared spectroscopy enable us also to obtain information about real crystalline microstructure and interior interactions of the semiconductor solid solutions (Barker Sievers, 1975 Robouch et al.,2001). 

Those, the high resolution FIR-spectra of the ternary HgCdTe and quaternary HgZnCdTe alloys obtained by using of the synchrotron radiation as source enable us to decipher the tangled phonon sp ctra in these kinds of the semiconductor solid solutions applying the random version of the V-B model for its interpretation.
