Structure and Surface Morphology of Cd1 −x(Mn, Fe)xSe Epitaxial Films

Аннотация

The optimal conditions (υ_к = 8−9 Å/s; Т_п = 673 K) to obtain structurally perfect (W_1/2 = 100″−140″) Cd_1 − x(Mn, Fe)_xSe epitaxial films in the (111) plane are determined. The structure and surface morphology of the epitaxial films are studied. It is established that in Cd_1 − x(Mn, Fe)_xSe thin films, unlike bulk samples, the sphalerite structure with the lattice parameter a = 6.05 Å is formed. Using an additional source of Se vapor during growth, Cd_1 − x(Mn, Fe)_xSe epitaxial films with a clean, smooth surface are obtained.
