Abstract

We present room-temperature measurements of the pressure dependence of the absorption edge of Zn1xMnxTe performed in a diamond-anvil cell. A blue shift of the direct gap with pressure, which decreases with manganese concentration, is observed. The absorption at energies below the direct gap is attributed to manganese and shows a red shift under pressure. They dominate the absorption structure at sufficiently high pressures and concentrations. A first-order phase transition limits the available pressure range: The transition pressure decreases drastically with manganese concentration.
