“…Thin films copper sulphide have been deposition by diverse preparation methods like reactive magnetron sputtering [14], alchemical bathroom precipitation [1,[15][16][17][18], drizzle pyrolysis [19], consecutive ionic stratum adsorption and reaction [20], microwave assisted chemical bath precipitation [21] , thermal steaming [9] and chemical vapor deposition [22]. In the present paper, thin films copper sulfide were prepared by thermic vaporization and the impact of 3% Al doping and then annealing at 573 K on structural and visual properties was attainment.…”

In this work Nano crystalline (Cu2S) thin films pure and doped 3% Al with a thickness of 400±20 nm was precipitated by thermic steaming technicality on glass substrate beneath a vacuum of ~ 2 × 10− 6 mbar at R.T to survey the influence of doping and annealing after doping at 573 K for one hour on its structural, electrical and visual properties. Structural properties of these movies are attainment using X-ray variation (XRD) which showed Cu2S phase with polycrystalline in nature and forming hexagonal temple ,with the distinguish trend along the (220) grade, varying crystallites size from (42.1-62.06) nm after doping and annealing. AFM investigations of these films show that increase average grain size from 105.05 nm to 146.54 nm while decrease the roughness from 5.93 nm to 4.73 nm after doping. Hall measurements show that the conductivity change from 1.43 × 10− 3 to 7.33 × 103 (Ω cm)-1 , these films have p-type conductivity and the mobility varied from 3.87 × 102 to 8.48 × 1010 cm2 /V.s. Optical constants were calculated for these films in the range of wave length (300-1100) nm using UV/Visible measurement. The visual properties showed that Cu2S membrane have a high value of the absorption coefficient and decrease the optical energy gap values from (2.25-1.5) eV after doping with 3% Al. The characterization of these films can chose in the application of solar cells.

“…As x increases, I sc also increases and attains a maximum value at x equal to 2 [6]. Many methods have been developed to prepare Cu 2 S thin films, such as solid state reaction [7], chemical vapor deposition (CVD) [8], spray pyrolysis [9], chemical bath deposition (CBD) [10][11][12][13][14], microwave assisted chemical bath deposition [15] and successive ionic layer adsorption and reaction (SILAR) [16][17][18]. The CBD technique is well known as a prevalent low-temperature aqueous technique for deposing thin films, the simplest and the economical one.…”
