Abstract
AbstractThe electrical conduction versus magnetic field in p‐like CdHgTe samples at 77 K is investigated by analysing the conductivity tensor components. The electrical conduction is mainly due to electrons in the conduction band and low‐mobility carriers in an impurity band. In the investigated samples CdxHg1–xTe with the composition x ≈ 0.17 the concentration of electrons in the conduction band is higher than the intrinsic one and in samples with the composition close to HgTe the concentration of electrons in the conduction band is equal to or lower than the intrinsic one. The model of a half‐filled impurity band situated close to the bottom of the conduction band is proposed to account for the concentration of electrons in the conduction band.
