Investigation of seeded vertical gradient freeze (VGF) growth of CdZnTe bulk crystals Balbaşı, Özden Başar; Ünal, Mustafa; Genç, Ayşe Merve; ÇELİK, GÜLÇİN; Parlak, Mehmet; Turan, Raşit (2022-04-15) © 2022 Elsevier B.V.Due to the requirement for superheating above the melting point in the homogenization process of CdZnTe material, complete seed melting remains as a significant problem for the seeded vertical gradient ...
Interface stability problem towards the end of THM growth of cadmium zinc telluride crystals Ünal, Mustafa; Balbaşı, Özden Başar; Genç, Ayşe Merve; Parlak, Mehmet; Turan, Raşit (2022-04-15) Growth of CdZnTe crystals by Travelling Heater Method (THM) is widely investigated by different groups. Interface shape and stability are critical parameters for the successful growth of high-quality CZT crystals. Even tho...
Production of High-Performance CdZnTe Crystals Grown by THM for Radiation Detection Applications Ünal, Mustafa; Balbaşı, Özden Başar; Karaman, Mehmet Can; Genç, Ayşe Merve; Parlak, Mehmet; Turan, Raşit (2022-01-01) © 2022, The Minerals, Metals & Materials Society.CdZnTe crystals are the perfect candidate to be used in room temperature x-ray and gamma-ray detection systems. Production of detector-grade crystals, on the other hand, is ...
Implementation of generalized Harvey-Shack theory in light scattering from rough surfaces Gunoven, M.; Nasser, H.; Ünal, Mustafa; Aytekin, O.; Turan, Raşit; Bek, Alpan (2020-12-01) We present a discrete implementation of generalized Harvey-Shack scalar scattering theory to calculate angular intensity distributions from height profiles of select randomly textured surfaces proposed for use in solar cel...
Alternative HF-free etching solution for aluminum induced texturing of glass surface with improved haze Ünal, Mustafa; Turan, Raşit (IOP Publishing, 2019-08-01) Aluminum induced texturing (AIT) is a promising surface conditioning method applied on glass substrates. In conventional AIT process, the reaction products (i.e., Al2O3 and Si) are stripped off the glass surface using an H...
A study on the performance the CdZnxTe1-x radiation detectors grown by vertical gradient freeze (VGF) technique Bender, Deniz; Turan, Raşit; Ünalan, Ayşe Merve; Ünal, Mustafa; Balbaşı, Özden Başar; Yılmaz, Ercan (null; 2019-06-14)

Growth, Wafering and Surface Preparation of CdZnTe Crystals for X–ray and Gamma Ray Applications Ünal, Mustafa; Balbaşı, Özden Başar; Kabukcuoğlu, Merve P; Ergunt, H Yasin; Parlak, Mehmet; Turan, Raşit (null; 2018-09-20)
CdZnTe Bulk Crystal Growth and Temperature Modeling Studies at METU-CGL Balbaşı, Özden Başar; DOĞRU, ÇİĞDEM; Kabukcuoglu, Merve; Ünal, Mustafa; Parlak, Mehmet; Turan, Raşit (2018-08-21) Cadmium Zinc Telluride (Cd1-xZnxTe) has become a crucial material for X-ray and gamma ray detection due to its wide band-gap, high atomic number and high density, which offer high efficiency and sharp spectroscopic resolut...
Optimization of chemical polishing by bromine-alcohol for detector-grade CdZnTe crystals and its effect on contacts Ünal, Mustafa; Balbaşı, Özden Başar; Ergunt, H Yasin; Turan, Raşit (2018-08-19) Cadmium Zinc Telluride (CdZnTe) is a good candidate for detection of x-ray and gamma-rays due to its high atomic number and large bandgap. CdZnTe is a II-VI group semiconductor and by changing ZnTe concentration, its prope...
