Formation of CuxS thin films through a chemical bath deposition process

Synthesis of nanostructured CuxS thin films by chemical route at room temperature and investigation of their size dependent physical properties

“…Bezig et al [17] have used vacuum evaporation technique to prepare Cu x S thin films. Fatas et al [18] have used CuSO 4 and thiourea in alkaline medium to deposit Cu x S thin films by chemical method and reported that their optical band-gap and resistivity is of the order of 2.58 eV and 3 × 10 −3 cm, respectively.…”

Optimization of the synthesis and characterizations of chemical bath deposited Cu2S thin films

“…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.…”

“…The electrical resistivity was of the order of 3.85 Â 10 À4 V-cm. The transmission and reflection coefficients vary in the range of [35-60] % and[5][6][7][8][9][10][11][12][13][14][15] % respectively, in the visible range, and the band gap energy is about 2.37 eV. ß 2010 Acadé mie des sciences.…”

Growth Kinetics of Copper Sulfide Thin Films by Chemical Bath Deposition

“…acidic or alkaline). 9,12,13,[19][20][21] However, no quantitative kinetic study of CBD Cu x S thin film growth has been reported in these studies. In-situ measurements are valuable and effective means to gain a better and more quantitative understanding of CBD Cu x S thin film growth mechanism and kinetics.…”
