Model Of The Two Well Potential For Hg-Atoms In The Hg1-Xcdxte Alloy Lattice

The problem of the additional phonon modes (APM) of the far infrared spectra in the range of 100-115 cm(-1) for the Hg1-xCdxTe alloys has been discussed for the last forty years. The model of two well potential of the mercury atoms in the Hg1-xCdxTe lattice is proposed for interpretation of these APM. Analysis was performed for samples of different compositions (0.06 < x < 0.7) and different types (n- and p-type) of conductivity.
