Transport Properties of n Type Cd_3−xZn_xAs₂ Alloys

Abstract

Measurements of the Hall and magneto-Seebeck effects were performed on polycrystalline Cd 3−x Zn x As 2 alloys at room temperature. The range of x considered here (0 to 1) is characterized by samples which are normally n type. Analysis of the data with Kane's model gives a minimum of the matrix element P at x = 0.6 which is interpreted as the manifestation of the band crossover suggested by Wagner et at. The scattering parameter also exhibits a minimum but at x ~ 0.2. A possible explanation may involve the manner in which the zinc atoms occupy the lattice vacancies.
