Abstract
A nanocomposite film consisting of crystalline CuSe and amorphous selenium (a-Se) was obtained by vacuum-thermal deposition. It has been shown for the first time that thermal heating of a CuSe/a-Se nanocomposite film in vacuum can transform it into a textured CuSe(006) film. It has been established that at a temperature of 438 K, CuSe crystallites grow intensively in the (006) crystallographic plane. Using the X-ray diffraction analysis method and the technique for measuring the electrical resistance of the CuSe/a-Se composite film, the phase transformation temperatures at which monoclinic Se8, trigonal t-Se, orthorhombic CuSe2, and hexagonal CuSe are formed.
