    Carrier scattering mechanisms in P-type indium selenide

    Carrier scattering mechanisms in p-indium selenide are investigated by means of the temperature dependence of the Hall mobility (160–500 K) and thermopower (200–300 K). An anomalous behaviour of the Hall volta...

    Excitonic absorption and Urbach's tail in bismuth sulfide single crystals

    The absorption coefficient of bismuth sulfide single crystals has been measured through more than four orders of magnitude and in the range of energies from 1.25 to 1.70 eV. A detailed study as a function of t...

    Tin-related shallow donor in indium selenide

    Hall-effect measurements in indium selenide samples doped with different amounts of tin are reported. The temperature dependance of free-electron concentration is interpreted through a single-donor single-acce...

    Acceptor levels in indium selenide. An investigation by means of the Hall effect, deep-level-transient spectroscopy and photoluminescence

    Acceptor levels related to I, II, IV, and V group impurities in indium selenide are studied by means of the Hall effect, deep-level-transient spectroscopy (DLTS) and photoluminescence. Activation energies for ...

    Optimization and Limitations of ITO/p-InSe/Au Solar Cells

    In this work we report the attempts to optimize the geometry and electrical parameters of ITO/p-InSe/Au solar cells. An increase of solar efficiency from 8% to 10% has been accomplished by vacuum annealing the...
