    Infrared spectroscopy of Cr- and V-doped Sb2Te3: Dilute magnetic semiconductors

  • Original language description

    Temperature dependent optical reflectance measurements on well characterized samples of nonintentionally doped, Cr-doped, and V-doped Sb2Te3 show that both the parent compound and the Cr-doped version are narrow-gap semiconductors (E-g approximate to 0.25 eV) with a conventional Drude free carrier absorption. The carrier density increases slightly with decreasing temperature while the scattering rate increases quadratically with temperature, which is a sign of the importance of optical phonon scattering. Vanadium doping introduces a change in the temperature dependence of the scattering rate as well as higher electrical resistivity than Cr-doped Sb2Te3. An analysis of the literature values of the saturation magnetization of Sb2-xVxTe3 for H parallel toc suggests V is in a mixed valence state V3+/V4+.
