The analysis of temperature dependent electrical resistivity and carrier concentration reveals the extrinsic type of conduction with a donor impurity level located at 0.44 eV, donor and acceptor concentrations of 3.4x10(17) and 4.1x10(17) cm(-1), respectively, and an electron effective mass of 0.41 m(o). The Hall mobility is limited by the electron-phonon short-range interactions scattering at high temperatures combined with the ionized impurity scattering at low temperatures. The electron-phonon short-range interactions scattering mobility analysis reveals an electron-phonon coupling constant of 0.25 and conduction band deformation potential of 5.57 eV/Angstrom.eninfo:eu-repo/semantics/closedAccessGaS0.5Se0.5 crystalsresistivityHall mobilityscattering mechanismsArticleQ3376587594WOS:000176200200007
