N-type to p-type crossover in quaternary BixSbyPbzSe3 single crystals

Original language description

We report on the preparation and some physical properties of a new type quaternary system based on Bi2Se3 co-doped with Sb and Pb. Single crystal samples were prepared using the Bridgman technique and were characterized by measurements of the lattice parameters, electrical resistivity, Hall coefficient, Seebeck coefficient and thermal conductivity. Atomic emission spectroscopy was used to find the concentration profiles of Sb and Pb along the single-crystalline ingots. Progressive co-doping of the Bi2Se3 crystal lattice with Sb and Pb leads to a crossover of the initially n-type conduction to that of the p-type. It is assumed that both Sb and Pb enter the Bi-sublattice. Physical properties as well as the change in the dominant carrier type are discussed in the context of the concentration of various point defects. A new complex defect is introduced to account for some features of the data.
