Abstract
Thin bismuth films of thickness in the range from 20 to 250 nm were prepared by thermal evaporation under vacuum conditions of 10-4 Pa. The ·films were deposited onto mica discs and quartz with the rate of 2 nm/s. The values of refractive index, extinction coefficient, dielectric constant, optical conductivity and some physical data of bismuth films were estimated in the infrared and visible region by using transmission technique.
