Özet

γ-MnS thin films were deposited on glass substrates by chemical bath deposition at different temperatures (27 °C, 40 °C and 70 °C). These films were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX) and optical absorption spectra. The obtained films exhibit hexagonal structures through the (002) plane with a varied grain size of between 241 Å and 318 Å. The band gap energy is found to be in the range of 3.40-3.80 eV. Moreover, electrical conductivity and mobility of the films were determined from the room temperature Hall measurements, which show that the obtained films have n-type conductivity and electrical conductivity, and mobility values change in the range (4.3-9.9) × 10-6 (Ω cm)-1 and 80-350 cm2 V-1 s-1, respectively. The influence of the bath temperature on the structural, optical and electrical properties of γ-MnS films was investigated and it was concluded that a growth temperature of 70 °C is suitable for producing γ-MnS films by chemical bath deposition technique, and the properties found in these films show their feasibility for technological purposes, especially for solar cells. © 2013 Elsevier B.V.
