Surface and interface chemistry of bromine–methanol-etched Cd0.9Zn0.1Te crystals
Ünal, Mustafa; Karaman, Mehmet Can; Çelik, Gülçin; Tüzel, Okay; Balbaşı, Özden Başar; Genç, Ayşe Merve; Turan, Raşit (2024-01-01)
Chemical polishing or chemo-mechanical polishing is crucial as a last step of surface preparation to remove the damaged layer and contaminants from the surface of CdZnTe crystals. The bromine–methanol solution is widely us...
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
