The present paper reports the structural and optical properties of thermally evaporated TlGaSe2 thin films. X-ray diffraction pattern of evaporated film presented two diffraction peaks around 24.15 and 36.00° which are associated with planes of monoclinic unit cell. Surface morphology of the TlGaSe2 thin films was investigated by scanning electron and atomic force microscopy techniques. Although there was observed some ignorable amount of clusters of quasi-spherical shape in the scanning electron microscope image, the film surface was observed almost uniform. Raman spectrum exhibited six peaks around 253, 356, 488, 800, 1053 and 1440 cm−1 associated with possible vibrational mode combinations. Band gap energy of the thin film was determined as 3.01 eV from the analyses of transmission spectrum. Transmission spectrum presented strong Urbach tail and analyses of corresponding region resulted in Urbach energy of 0.66 eV. The structural and optical properties of deposited TlGaSe2 thin films were compared with those of single crystal. This comparison would provide valuable information about influence of thickness on the studied compounds.

Structural and optical properties of Zn-In-Te thin films deposited by thermal evaporation technique
Gullu, H. H.; Bayrakli, O.; CANDAN, İDRİS; COŞKUN, EMRE; Parlak, Mehmet (2013-07-25)
Annealing effects on structural and optical properties of the thermally evaporated Zn-In-Te(ZIT) thin films have been investigated. The structural and the compositional analyses were carried out by means of X-ray diffraction (XRD) and energy dispersive X-ray analysis (EDXA). The as-grown and annealed ZIT films had polycrystalline structure and the preferred orientation changed from (220) to (112) direction with increasing annealing temperature. The optical properties and constants were determined by transmi...
Structural and optical properties of thermally evaporated Ga-In-Se thin films
IŞIK, MEHMET; Güllü, Hasan Hüseyin (2014-05-30)
In this paper, structural and optical properties of Ga-In-Se (GIS) thin films deposited by thermal evaporation technique have been investigated. The effect of annealing was also studied for samples annealed at temperatures between 300 degrees C and 500 degrees C. X-ray diffraction, energy dispersive X-ray analysis and scanning electron microscopy have been used for structural characterization. It was reported that increase of annealing temperature results with better crystallization and chemical composition...
Structural, optical and electrical characterization of CDSEXTE1-X thin films
Demir, Merve; Parlak, Mehmet; Department of Physics (2020)
The aim of this study is to investigate the structural, optical and electrical properties of ternary CdSexTe1-x thin films. CdTe and CdSe thin films are being used in solar cells due to their favorable direct band gaps of 1.5eV and 1.7eV, respectively. Moreover, having high absorption coefficients provide an important role to CdTe and CdSe films as an absorber layer. Therefore, by mixing these two films, properties of resultant ternary CdSexTe1-x alloy can be optimized for solar cell applications. Chemical ...
Structural and optical properties of thermally evaporated Cu-Ga-S (CGS) thin films
Gullu, H. H.; IŞIK, MEHMET; Hasanlı, Nızamı (2018-10-15)
The structural and optical properties of thermally evaporated Cu-Ga-S (CGS) thin films were investigated by Xray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS), atomic force microscopy (AFM) and optical transmittance measurements. The effect of annealing temperature on the results of applied techniques was also studied in the present paper. EDS results revealed that each of the elements, Cu, Ga and S are presented in the films and Cu and Ga concentration increases whereas S concentration decr...
Structural and temperature-dependent optical properties of thermally evaporated CdS thin films
IŞIK, MEHMET; Gullu, H. H.; Delice, S.; Parlak, Mehmet; Hasanlı, Nızamı (Elsevier BV, 2019-04-01)
In this work, structural and temperature dependent optical properties of thermally evaporated CdS thin films were investigated. X-ray diffraction, energy dispersive spectroscopy and Raman spectroscopy experiments were carried out to characterize the thin films and obtain information about the crystal structure, atomic composition, surface morphology and vibrational modes. Temperature-dependent transmission measurements were performed in between 10 and 300 K and in the spectral range of 400-1050 nm. The anal...
