Electrical conductivity, defect density and structure of obliquely vacuum-deposited tin antimonide alloy thin films

Abstract: Thin films of tin antimonide alloy have been vacuum deposited on glass substrates at room temperature at different angles of deposition. These films have been heat-treated in situ and their electrical resistance has been continuously monitored during the heating-cooling cycle. From the resistance against temperature data during heat-treatment, “initial lattice distortion energy spectra” of these films have been determined using Vand's theory. It has been found that for angles of deposition below 50°, the defect density increases with increasing angle of deposition. At higher angles of deposition, the resistance against temperature behaviour during heat-treatment is different. This is attributed to the columnar structure of the film. It is also found that preferential decay energies of the defects exist and these are 1.45 and 1.80 eV.
