Chen, Tianyi; Gigax, Jonathan G.; Price, Lloyd; Chen, Di; Ukai, S.; Aydoğan Güngör, Eda; Maloy, S. A.; Garner, F. A.; Shao, Lin (Elsevier BV, 2016-09-01)
In this study, the microstructure of a 12Cr ferritic-martensitic oxide-dispersion-strengthened (ODS) alloy is studied before and after Fe ion irradiation up to 200 peak displacements per atom (dpa). Irradiation temperature ranges from 325 to 625 degrees C. Before irradiation, both coherent and incoherent dispersoids exist in the matrix. In response to irradiation, the mean sizes of dispersoids in both the ferrite and tempered martensite phases change to equilibrium values that increase with irradiation temp...
Temperature -dependent optical and electrical characterization of Cu-Ga-S thin films and their diode characteristics on n-Si
Gullu, H. H.; Isik, M.; Hasanlı, Nızamı; Parlak, Mehmet (Elsevier BV, 2020-04-01)
In this paper, optical and electrical properties of thermally deposited Cu-Ga-S thin films were investigated using temperature-dependent optical transmission and electrical conductivity measurements. The analysis of the transmission spectra resulted in formation of three direct optical transitions due to the possible valence band splitting in the structure. The band gap values were calculated by means of absorption coefficient and incident photon energy was found in decreasing behavior as the temperature ri...
Temperature dependent band gap in SnS2xSe(2-2x) (x=0.5) thin films
Delice, S.; Isik, M.; Gullu, H. H.; Terlemezoglu, M.; Surucu, O. Bayrakli; Hasanlı, Nızamı; Parlak, Mehmet (Elsevier BV, 2020-08-01)
Structural and optical properties of SnS2xSe(2-2x) thin films grown by magnetron sputtering method were investigated for composition of x = 0.5 (SnSSe) in the present study. X-ray diffraction, energy dispersive X-ray spectroscopy, atomic force microscopy and scanning electron microscopy methods were used for structural characterization while temperature-dependent transmission measurements carried out at various temperatures in between 10 and 300 K were accomplished for optical investigations. X-ray diffract...

Gullu, H. H.; YILDIZ, DİLBER ESRA; Surucu, O. Bayrakli; Terlemezoğlu, Makbule; Parlak, Mehmet (Springer Science and Business Media LLC, 2019-04-01)
Cu2ZnSnTe4 (CZTTe) thin films with In metal contact were deposited by thermal evaporation on monocrystalline n-type Si wafers with Ag ohmic contact to investigate the device characteristics of an In/CZTTe/Si/Ag diode. The variation in electrical characteristics of the diode was analysed by carrying out current-voltage (I-V) measurements in the temperature range of 220-360 K. The forward bias I-V behaviour was modelled according to the thermionic emission (TE) theory to obtain main diode parameters. In addit...
Temperature dependence of band gaps in sputtered SnSe thin films
Delice, S.; Isik, M.; Gullu, H.H.; Terlemezoğlu, Makbule; Bayrakli Surucu, O.; Parlak, Mehmet; Hasanlı, Nızamı (Elsevier BV, 2019-08-01)
Temperature-dependent transmission experiments were performed for tin selenide (SnSe) thin films deposited by rf magnetron sputtering method in between 10 and 300 K and in the wavelength region of 400-1000 nm. Transmission spectra exhibited sharp decrease near the absorption edge around 900 nm. The transmittance spectra were analyzed using Tauc relation and first derivative spectroscopy techniques to get band gap energy of the SnSe thin films. Both of the applied methods resulted in existence of two band ga...
