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:: We report on experiments on low temperature (millikelvin range) activated magnetotransport on low-density two-dimensional electron systems in InGaAs/InP for Landau level filling factors 0.25 ≤ ν ≤ 0.55. The activation energy increases approximately linearly with decreasing filling factor. The observations are discussed in the light of the formation of the Wigner solid.

Opis:: The energy relaxation in two-dimensional electron gas in In$\text{}_{0.53}$Ga$\text{}_{0.47}$As/InP has been studied in a wide range of electron temperatures (from 0.1 to 10 K). The energy loss rate of electrons is controlled by the interaction of electrons with the piezoelectric potential of acoustic phonons. The value of the piezoelectric constant for InGaAs lattice-matched to InP is deduced from theoretical fits of the experimental data: h$\text{}_{14}$=(1.1±0.1)×10$\text{}^{7}$ V/cm. Available data for the piezoelectric constant of In$\text{}_{x}$Ga$\text{}_{1-x}$As are discussed in the light of the results of this work.
