QUIROZ, Heiddy P.  y  DUSSAN, Anderson. INFLUENCE OF THE SUBSTRATE TEMPERATURE ON OPTICAL AND STRUCTURAL PROPERTIES OF GaSb: Ni ALLOYS. Momento [online]. 2018, n.56, pp.17-25. ISSN 0121-4470.  https://doi.org/10.15446/mo.n56.69822.

GaSb: Ni ternary alloys thin films were deposited via sputtering method (DC magnetron Co-Sputtering) varying the substrate temperature (Ts). From spectra transmittance measurements and X-ray diffraction (XRD) were obtained the optical constants and structural properties of material, respectively. Predominant phases of GaSb and NiSb were observed for all Ts variations. From absorption measurements, the value of energy band forbidden or "band gap" was obtained varying between 0,63 eV and 0,72 eV. The extinction coefficient κ as a function of wavelength of the GaSb:Ni thin films, was reported.
