Effective role of cadmium doping in controlling the linear and non-linear optical properties of non-crystalline Cd–Se–S thin films

Cadmium atoms were used to dope the non-crystalline SeS thin films prepared at 298 K using a vacuum evaporation. The prepared thin films (~ 300 nm) were according to the Cd x Se 85 S 15- x system and in the corresponding proportions ( x  = 0, 5, 10, and 15 at.%). In this process, pure film and three...

Zusammenfassung:Cadmium atoms were used to dope the non-crystalline SeS thin films prepared at 298 K using a vacuum evaporation. The prepared thin films (~ 300 nm) were according to the Cd x Se 85 S 15- x system and in the corresponding proportions ( x  = 0, 5, 10, and 15 at.%). In this process, pure film and three cadmium-doped films were obtained. Structural analysis was utilized to confirm the amorphous nature of the pure and Cd-doped thin films. A tremendous effort has been devoted to accurate and flexible detailing of the linear and non-linear optical properties of the studied system. The linear optical path in this work was based on calculating the absorption coefficient, the optical parameters, the optical constants, the dielectric constants, the quality factor of thin films, the dispersion parameters, the optical dispersion coefficients, phase and group velocities, Verdet’s coefficients, and Kirchhoff’s functions were determined. As well, the non-linear optical qualities have been computed.
