Properties of solid solution (Cd0.69Zn0.31)3As2

Condensed matter physics

The modified Bridgeman method was used to obtain single crystals of (Cd0.69Zn0.31)3As2. It has been established that the studied sample crystallizes in space group P42/nmc with lattice parameters a = 8.78 Å, b = 12.42 Å. We have investigated the electrical conductivity in the temperature range from 10 to 300 K and in a magnetic field of 1 T, and determined the temperature dependences of the concentration and mobility of charge carriers. We have established that hopping conduction with a variable length of the Mott-type hop takes place in the temperature range from 10 to 33 K, and determined its micro parameters.
