Mechanism and characterization studies on boron carbides deposited by chemical vapor deposition technique
Karaman, Mustafa; Özbelge, Hilmi Önder; Sezgi, Naime Aslı; Doğu, Timur (2005-12-02)
Boron carbide was produced in an impinging jet CVD reactor from a gas mixture of BCl3, CH4 and H-2. The mass transfer limitations on the reaction kinetics were minimised by the jet impingement on the substrate surface. XPS characterization of the produced deposits revealed a nearly pure boron carbide phase containing small amounts of oxy-boron and oxy-carbon species. After a detailed kinetic study, a reaction model was proposed to predict the rates of boron carbide and dichloroborane formation reactions. In...

Investigation of material properties of magnetron sputtered CuAg-In-Se thin films
Güllü, Hasan Hüseyin; Parlak, Mehmet (null; 2016-09-23)
Thin films of copper based chalcopyrite absorber materials are attracting the attention of many researchers because of their favorable optoelectronic properties and good stability makes them suitable for photovoltaic and optoelectronic device applications. These compounds are particularly suitable for making p-n hetero-junctions with the II-VI compounds. Therefore, the utilization of I-III-VI2 group of chalcopyrite semiconductors has been reported in the literature for application in thin film solar cells. ...

The nonlinear optical absorption of InSe, GaSe and GaxIn1-xSe amorphous films with varying thickness and doping has been studied by open-aperture Z-scan experiment with 4 ns and 65 ps pulse durations at 1064 nm wavelength and femtosecond pump-probe spectroscopy. Our results show that the dopant and film thickness (from 20 nm to 104 nm) results in switching from saturable absorption to nonlinear absorption for equal input intensities. This behaviour is attributed to increasing localized defect states with in...
Investigation of the electromagnetic properties of single walled carbon nanotube thin films
Küçükyıldız, Şeyda; Dericioğlu, Arcan Fehmi; Ünalan, Hüsnü Emrah; Department of Metallurgical and Materials Engineering (2013)
The work presented in this thesis can be divided in two parts. First part discusses the dispersion and deposition routes of single walled carbon nanotube (SWNT) thin films. Two different types of SWNTs and several dispersing agents were examined to achieve a homogeneous SWNT solution. A tip-sonicator and an ultrasonic bath was compared and it has been found that tip-sonicator increases the efficiency of SWNT dispersions. Vacuum filtration and spray coating techniques were utilized for the deposition of SWNT...
