The electrical properties of Cu2Te

The conductivity, Hall effect, and thermo-emf are reported for thin films and polycrystalline bulk specimens of Cu₂Te, which is found to be an impurity semiconductor whose forbidden band has a width of 0.9–1.0 eV. The compound dissociates on vacuum evaporation, so it is very difficult to produce thin films.I am indebted to Professor D. N. Naskedov for his interest and for valuable comments.
