Opis:: Hole concentration and mobility were investigated by Hall measurements in nominally undoped p-type GaSb in the temperature range from 77 to 300 K. The dependence of the thermal ionization energy of native acceptors on the acceptor centre concentration and on the compensation degree was determined. The temperature dependence of the hole mobility was analyzed using a heuristic semi-empirical model as well as using a phenomenological two-hole band model. Space charge scattering and/or dipole scattering described with a mobility contribution with a~ T$\text{}^{-1}\text{}^{/}\text{}^{2}$ like temperature dependence dominated the hole mobility in the investigated temperature range.

Opis:: High purity In$\text{}_{0.53}$Ga$\text{}_{0.47}$As layers were grown on semi-insulating InP:Fe substrates by liquid phase epitaxy by adding small amounts of dysprosium (rare earth) to the melt. Hall effect and photoluminescence measurements showed that the addition of Dy strongly reduced the carrier and residual donor concentration, with a concurrent shift of the excitonic luminescence toward higher energies. The observed effects are ascribed to the gettering of residual donor impurities in the melt by Dy, as well as to the effects of possible incorporation of Dy into the grown layers.
