Optical and Morphology Properties of Cu2Se at Different Temperatures by Thermal Evaporation	2025	10	.pdf	application/pdf	3680	277	60	Deposition of thin films Cu2Se by vacuum thermal evaporation in glass substrates at R.T with (500+-20) nm thickness, then annealing at (403, 453, and 503) K in an electric furnace for 60 minutes. The surface morphology, roughness and Grain Size of Cu2Se were shown to be affected by annealing temperature using atomic force microscopy AFM (24), the optical properties of thin film prepared, transmission and absorption spectrums in the range between 400 to 1100 nm has been noted, lambert law and Tauc equation have been used to determine the absorption coefficients α and the energy gap (Egopt) respectively from absorption spectrum (25, 26).	cache/iajs-4122.pdf	txt/iajs-4122.txt
