Ag-doped In2S3(In2S3:Ag) thin films have been deposited onto glass substrates by a thermal evaporation method. Ag concentration is varied from 0 at.% to 4.78 at.%. The structural, optical, and electrical properties are characterized using X-ray diffraction (XRD), spectrophotometer, and Hall measurement system, respectively. The XRD analysis confirms the existence of In2S3and AgIn5S8phases. With the increase of the Ag concentration, the band gap of the films is decreased gradually from 2.82 eV to 2.69 eV and the resistivity drastically is decreased from ~103to5.478×10-2 Ω·cm.

This work describe the optical and electrical properties of indium tin oxide (ITO) thin films prepared by thermal evaporation method on flexible plastic substrate (polyethylene terephthalate (PET)). The optical transmission and absorption of ITO films in the visible and UV rang have been studied. The resistivity, sheet resistant, carrier concentration and mobility have been evaluated by Hall Effect measurement. The surface morphology and roughness were investigated by atomic force microscopy (AFM). The results indicate that the optical transmission greater than 85% over the visible rang and it was found to be strongly dependent on the thickness of ITO films. The Resistivity and sheet resistant with low values (10-4Ω-cm, 9.22 Ω/ respectively) were obtained and ties values were increased with ITO thin films thickness increasing .AFM investigation showed that the roughness surface of (8 – 30) RMS have been obtained over different thickness of ITO films. The obtained results of the deposited films by this method were analyzed. Details of sample preparation, experimental methods and results are given and discussed.

The indium selenium (InSe) bilayer thin films of various thickness ratios, InxSe(1-x) (x = 0.25, 0.50, 0.75), were deposited on a glass substrate keeping overall the same thickness of 2500 Ǻ using thermal evaporation method under high vacuum atmosphere. Electrical, optical, and structural properties of these bilayer thin films have been compared before and after thermal annealing at different temperatures. The structural and morphological characterization was done using XRD and SEM, respectively. The optical bandgap of these thin films has been calculated by Tauc’s relation that varies within the range of 1.99 to 2.05 eV. A simple low-cost thermoelectrical power measurement setup is designed which can measure the Seebeck coefficient “S” in the vacuum with temperature variation. The setup temperature variation is up to 70°C. This setup contains a Peltier device TEC1-12715 which is kept between two copper plates that act as a reference metal. Also, in the present work, the thermoelectric power of indium selenide (InSe) and aluminum selenide (AlSe) bilayer thin films prepared and annealed in the same way is calculated. The thermoelectric power has been measured by estimating the Seebeck coefficient for InSe and AlSe bilayer thin films. It was observed that the Seebeck coefficient is negative for InSe and AlSe thin films.
