Abstract
The components of resistivity (ρij), Hall coefficient (Rijk), and magnetoresistance (ρij, kl) of n-Bi0.88Sb0.12 single crystals doped with tellurium to 0.01, 0.1, and 0.2 at % have been measured in the temperature range of 77–300 K. It is concluded that light and heavy electrons are involved in transport processes. The energy spacing between the bands of light and heavy electrons is found to be 40 meV, and the ratios of the effective masses and electron mobilities are estimated as m2*/ml* = 3 and b ≈ 0.16, respectively.
