- Abstract
The growth of epitaxial films of PbSnSe solid solutions of different chemical compositions ( x = 0.02-0.05) on freshly cleaved BaF(111) faces and the structure of these films have been investigated. Photosensitive p- n homojunctions have been prepared on their basis. The homojunctions are fabricated in a unified technological cycle without breaking vacuum based on n- and p-type films of high structural quality ( W = 90-100″) that were grown using an additional selenium vapor source. The photosensitivity peak is found to shift to longer wavelengths with an increase in the Sn content in the films grown; this effect is explained by narrowing the band gap with a change in the composition.
