Abstract

The effect of pressure on the electronic band structure of Zn_1-yMn_yO_xTe_1-x alloys was studied by investigating the optical transitions associated with the Τ point at the conduction-band and the valence-band edges. The Zn_1-yMn_yO_xTe_1-x samples were found to exhibit a classical band-anticrossing behavior with the formation of two conduction subbands resulting from the strong interaction between the extended conduction-band states of Zn_1-yMn_yTe and the localized O states. By examining the effect of applied pressure on the E_ transition, the energetic position of E_D=E_V+2.0±0.1 eV for the localized O level and its pressure dependence of 0.6±0.1 meV/kbar were derived from the experimental results.
