Electroreflectance study of Hg1−xMnxTe in the E1 and E1+Δ1 energy regions

Abstract
We report electrolyte electroreflectance studies of the ternary semimagnetic semiconductor Hg1−xMnxTe for compositions below x=0.2. The dependence of E1 and E11 transition energies on the composition was determined on the basis of the low field approximation. The present results are compared and discussed in relation to experimental data obtained previously and the theoretical predictions reported in the literature.
