Deposition of CZTSe thin films and illumination effects on the device properties of Ag/n-Si/p-CZTSe/In heterostructure Bayrakli, O.; Terlemezoğlu, Makbule; GULLU, H. H.; Parlak, Mehmet (2017-06-30) Characterization of Cu2ZnSnSe4 (CZTSe) thin films deposited by thermal evaporation sequentially from the pure elemental sources and in-situ post annealing was carried out at 400 C under Se evaporation atmosphere. Another annealing process was applied in nitrogen atmosphere at 450 degrees C to get poly-crystalline monophase CZTSe film structure. XRD analysis together with Raman spectroscopy was used to determine the structural properties. Spectral optical absorption coefficient evaluated from transmission da...

Deposition and characterization of layer-by-layer sputtered AgGaSe2 thin films KARAAĞAÇ, HAKAN; Parlak, Mehmet (Elsevier BV, 2011-04-15) Sputtering technique has been used for the deposition of AgGaSe2 thin films onto soda-lime glass substrates using sequential layer-by-layer deposition of GaSe and Ag thin films. The analysis of energy dispersive analysis of X-ray (EDXA) indicated a Ga-rich composition for as-grown samples and there was a pronounce effect of post-annealing on chemical composition of AgGaSe2 thin film. X-ray diffraction (XRD) measurements revealed that Ag metallic phase exists in the amorphous AgGaSe2 structure up to annealin...
Deposition and Characterization of ZnSnSe2 Thin-Films Deposited by Using Sintered Stoichiometric Powder Bayrakli Surucu, Ozge; Güllü, Hasan Hüseyin (2019-09-01) In this work, ZnSnSe2 (ZTSe) thin films were deposited using crystalline powder grown by vertical Bridgman-Stockbarger technique. The deposition process was carried out by means of e-beam evaporation on the well-cleaned soda lime glass substrates and keeping them at the substrate temperature of 200 degrees C. The structural, optical and electrical properties of ternary ZTSe thin films were investigated depending on the annealing temperature at 250 and 300 degrees C. X-ray diffraction analysis showed that as...
Dissolution of colemanite and crystallization of gypsum during boric acid production in a batch reactor Erdoğdu, Anıl; Eroğlu, İnci; Department of Chemical Engineering (2004) One of the most commonly used boron compounds, boric acid, is produced by dissolving colemanite (2CaO₉3B2O3₉5H2O) in aqueous sulfuric acid whereby gypsum (CaSO4₉2H2O) is formed as a byproduct and must be separated from the main product. This process consists of two steps, dissolution of colemanite and formation of gypsum. The amount of boric acid formed depends on the first step, dissolution of colemanite. In the latter step, gypsum crystals are formed and stay in the reaction mixture to grow up to a size l...
