Growth of epitaxial Cd1-x Mn (x) Te films

摘要

We have studied the growth and structure of epitaxial films of Cd1-x Mn (x) (x = 0.03) diluted magnetic solid solutions grown on mica substrates by molecular beam epitaxy and identified conditions for producing n- and p-type epitaxial films. Using an additional Te vapor source and optimizing the substrate temperature in the growth process, we were able to obtain structurally perfect p-type Cd1-x Mn (x) Te (x = 0.03) films with clean, smooth surfaces. The growth plane of the films on the mica substrates is (111) of a face-centered cubic lattice and their unit-cell parameter is D degrees = 6.477 .
