The Optical Properties of Cadmium Sulfide Thin Films Prepared by co-evaporation Deposition Methods of CdS and Sulfur. Cadmium Sulfide Thin Films have been deposited by thermal co-evaporation methods of CdS + S. The films were prepared on glass substrate and were varied by changing these deposition rates into 4-16 AIs. The thickness of the films and the real part of refractive indexes have been determined based on interference method using maximum and minimum of reflectance spectrum. The optical parameters a of these films have been determined by reflectance and transmittance spectrum using Hishikawa formulation of T/(1-R). The real part of refractive index and optical parameter a reduce with the higher deposition rate for transparency region - (E<2.6 eV). The optical gap almost did not show a certain tendency by deposition rate variation. The complex dielectric functions of these films reflect the real part of refractive indexes and extinction coefficients. Lapisan tipis CdS telah dideposisi dengan metode co-evaporasi termal CdS+S. Lapisan tipis dideposisi di atas substrat kaca dan divariasi laju deposisinya 4 -16 AIs. Ketebalan dan indeks bias lapisan tipis ditentukan berdasarkan prinsip interferensi dengan menggunakan maksimum dan minimum spektrum reflektansi. Parameter optis a lapisan tipis ditentukan dari spektrum reflektansi dan transmitansi dengan menggunakan formulasi Hishikawa T/(1-R). Indeks bias rill dan parameter optis a berkurang dengan meningkatnya laju deposisi di daerah transparan (E < 2.6 eV). Gap optis tidak menunjukkan kecenderungan tertentu dengan variasi laju deposisi. Fungsi dielektrik kompleks lapisan tipis CdS mewakili indeks bias riil dan koefisien ekstinksi. |
