Investigation of electrical conductivity and optical absorption in amorphous InXSe100-X alloys

Electrical and optical properties of thin film of a-Se70Te30 nanorods

“…The order of the calculated values of the absorption coefficient for a-Se 70 Te 30 film is of the order of ∼10 4 cm −1 , which is consistent with the result of other workers [46,47].…”

Electrical transport and optical properties of Zn doped Bi–Se chalcogenide glasses

“…At the low energy side, peaks are observed due to fundamental absorption and absorption due to impurities [21]. The calculated values of a for the thin films of Bi 0.5 Se 99.5−x Zn x system are of the order of 10 4 cm −1 , which are consistent with the results of other workers [22].…”

Thermal annealing effect of on optical constants of vacuum evaporated Se75S25−xCdx chalcogenide thin films

“…In amorphous materials, a increases exponentially with the photon energy near the energy gap. This type of behavior has also been observed in many other chalcogenides [14] and is given by [15,16]. The fundamental absorption edge in most amorphous semiconductors follows an exponential law.…”
