“…The reduction of transmission, increase in absorption coefficient and increase of the band gap of 0.05 eV from the as-prepared bilayer lm are due to the diffusion of Bi into the As 2 Se 3 matrix. The Bi layer has diffused into the As 2 Se 3 layer for a certain distance which depends on the diffusion length of Bi and has formed a three- This type of solid solution formation has been studied in other different types of lms [42][43][44] and is responsible for the increase in optical band gap of the irradiated lm. Aer inter-diffusion, the three-component Bi-As-Se solid solution is created with the decreasing width of the optical band gap in comparison with homogeneous amorphous As 2 Se 3 lm.…”
