Ft. Vasko et al., ANISOTROPY OF DIELECTRIC PERMITTIVITY IN UNIAXIALLY STRESSED NARROW-GAP SEMICONDUCTORS, UKRAINSKII FIZICHESKII ZHURNAL, 38(8), 1993, pp. 1201-1204
The strain-induced anisotropy of permittivity, caused by the virtual i
nterband transitions in narrow-gap semiconductors is studied. The grea
t phase shift between the waves polarized along and perpendicular to d
eformation with their propagation through the deformed crystal is pred
icted. Numerical calculations are made for InSb and Cd0.2Hg0.8Te.
