Space-charge-limited currents and photoconductive properties of Tl2InGaSe4 layered crystals QASRAWI, ATEF FAYEZ HASAN; Hasanlı, Nızamı (Informa UK Limited, 2008-01-01) The extrinsic electronic parameters of Tl2InGaSe4 layered crystals were investigated through measurement of the temperature-dependent dark conductivity, space-charge-limited currents and photoconductivity. Analysis of the dark conductivity reveals the existence of two extrinsic energy levels at 0.40 and 0.51 eV below the conduction band edge, which are dominant above and below 260 K, respectively. Current-voltage characteristics show that the one at 0.51 eV is a trapping energy level with a concentration of...
Crystallization and phase separation mechanism of silicon oxide thin films fabricated via e-beam evaporation of silicon monoxide Gunduz, Deniz Cihan; Tankut, Aydin; Sedani, Salar; Karaman, Mehmet; Turan, Raşit (2015-04-29) In this work, silicon oxide thin films were synthesized via e-beam evaporation of silicon monoxide. Subsequent annealing experiments were carried out to induce Si nanocrystals (Si NCs) formation. A broad range of annealing durations and temperatures were studied. Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and Fourier Transform Infrared Spectroscopy (FTIR) were employed to study the mechanism of phase separation in silicon oxide films and crystallization of Si. Raman spectroscopy results show...
Microstructural properties and local atomic structures of cobalt oxide nanoparticles synthesised by mechanical ball-milling process AKSOY, FUNDA; AKGÜL, GÜVENÇ; Kurban, Mustafa (Informa UK Limited, 2016-01-01) In this study, facile preparation of pure and nano-sized cobalt oxides particles was achieved using low-cost mechanical ball-milling synthesis route. Microstructural and morphological properties of synthesised products were characterised by X-ray diffraction (XRD) and transmission electron microscopy (TEM) techniques. XRD results indicated that the fabricated samples composed of cubic pure phase CoO and Co3O4 nanocrystalline particles with an average crystallite size of 37.2 and 31.8nm, respectively. TEM im...
Transport studies of carbon-rich a-SiCx : H film through admittance and deep-level transient spectroscopy measurements Atilgan, I; Ozdemir, O; Akaoglu, B; Sel, K; Katircioglu, B (Informa UK Limited, 2006-07-01) An intrinsic, carbon- rich a- SiCx: H thin film, prepared by the plasma- enhanced chemical vapour deposition ( PECVD) technique, has been studied mainly by AC admittance and small- pulse deep- level transient spectroscopy ( DLTS) measurements on an Al/ a- SiCx: H/ p- Si metal - insulator - semiconductor ( MIS) structure. The effects of measurement temperature, voltage and small- signal AC modulation frequency on the MIS capacitor are qualitatively and quantitatively described. The kinetics of charge injecti...
Optical Characterization of Amorphous Hydrogenated Carbon (a-C:H) Thin Films Prepared by Single RF Plasma Method Mansuroğlu, Doğan; GÖKŞEN, KADİR; Bilikmen, Sinan (IOP Publishing, 2015-06-01) Methane (CH4) plasma was used to produce amorphous hydrogenated carbon (a-C:H) films by a single capacitively coupled radio frequency (RF) powered plasma system. The system consists of two parallel electrodes: the upper electrode is connected to 13.56 MHz RF power and the lower one is connected to the ground. Thin films were deposited on glass slides with different sizes and on silicon wafers. The influence of the plasma species on film characteristics was studied by changing the plasma parameters. The chan...
