Özet

Resistivity, magnetoresistivity and Hall effect measurements in n-type Te-doped InSb and S-doped InAs samples grown by the liquid encapsulated Czochralski technique were carried out as a function of temperature (14-350 K) and magnetic field (0-1.35 T). In Te-doped InSb, an impurity level with energy E1 = 3 meV and the activation energy E0 = 0.26 e V, which is the band gap energy, are obtained from the resistivity and Hall carrier concentration analysis. In S-doped InAs, both the linear and power law models are used in explaining the temperature-dependent resistivity. The effects of impurities on the electron and magnetic transportation properties of InAs and InSb have also been discussed. © 2005 Chinese Physical Society and IOP Publishing Ltd.
