Research ArticleOpen accessIn the keywordsDetermining Optical Constants of Selenium Thin Films using the Envelope MethodNehad M. Tashtoush, Osamah ALkasassbehTwo Selenium thin films were deposited on glass substrates using thermal evaporation technique. The optical constants (refractive index, absorption coefficient and extinction coefficient and energy gap) were calculated using the Transmittance (T) spectrums of the films in the spectral range of 500-900 nm. The envelope method was used to determine optical constants. The calculated refractive index was found to be … …American Journal of Applied Sciences, Vol. 10, Issue 2 · 15 Feb 2013 · 6,337 accessesView PDF Cite
