Description

The composition and temperature dependence of the band gap and the lattice constants of the MgxCd 1-xSe crystals was investigated in the composition range of 0.00 ≤ x ≤ 0.46 and in the temperature range of 11 to 290 K. The lattice constants showed a composition dependence decreasing linearly with increasing composition x, and also showed a temperature dependence that the relative variation of the lattice constants with temperature is somewhat different from each other for all the crystals. The temperature dependent behavior of the lattice constants was also observed with an inverse trend in the temperature dependence of the band gaps. The temperature dependence of the band gaps was well fitted by the empirical Varshni equation for all the investigated compositions. The composition dependence of the band gaps was represented by the linear relationship of E g(x) = 1.742 + 1.813 x for 290 K and E g(x) = 1.828 + 1.871 x for 11 K.
