Tin-related double acceptors in gallium selenide single crystals

Abstract: Gallium selenide single crystals doped with different amounts of tin are studied through resistivity and Hall effect measurements in the temperature range from 30 to 700 K. At low doping concentration tin is shown to behave as a double acceptor impurity in gallium selenide with ionization energies of 155 and 310 meV. At higher doping concentration tin also introduces deep donor levels, but the material remains p-type in the whole studied range of tin doping concentrations. The deep character of donors in galli… Show more

“…The value is high enough to make GaSe:In potential candidates for room temperature radiation detectors although the dependences of hole mobility on temperature and indium concentration need further investigation to clarify the mechanism of hole scattering by the dopants and phonons. 8 The carrier mobility-lifetime product is an important figure of merit in the evaluation of x-ray and gamma-ray semiconductor detectors; the carrier lifetime is determined by the trap concentrations and the capture cross sections.…”

“…There are markedly many studies carried out to observe the influence of chemical doping in GaSe crystals with different elements, such as Cl [11], Sn [12][13], Cu [14], Li [15], Ag [16], and Zn [17]. Although chemical doping is the most commonly used method, it has some drawbacks since the dopant is added before the growth process.…”
