The effect of Sn doping Urbach Tail and optical absorbtion measurements of InSe crystal
Duman, Songül; Gürbulak, Bekir; Doǧan, Seydi; Özçelik, Fikriye Şeyma (Institute of Physics Publishing, 2016)InSe and n-InSe:Sn crystals grown by Bridgman-Stockbarger method. Absorption measurements have been carried out in InSe and InSe:Sn samples in the temperature range 10-320 K with a step of 10 K. Sn doping to InSe have ... -
Fabrication and characterization of Al/Cu2ZnSnS4/n-Si/Al heterojunction photodiodes
Turgut, Güven; Keşkenler, Eyüp Fahri; Aydın, Serdar; Doğan, Seydi; Duman, Songül; Özçelik, Şeyma; Gürbulak, Bekir; Esen, Bayram (Wıley-V C H Verlag Gmbh,, 2014)Cu2ZnSnS4 (CZTS) thin film has been synthesized by a sol-gel spin-coating technique on the n-Si substrate to fabricate heterojunction photodiodes. An X-ray diffraction study has shown that the film is polycrystalline with ... -
Growth and characterization of Ag/n-ZnO/p-Si/Al heterojunction diode by sol-gel spin technique
Keskenler, Eyüp Fahri; Tomakin, Murat; Doǧan, Seydi; Turgut, Güven; Aydın, Serdar; Duman, Songül; Gürbulak, Bekir (Elsevier Science Bv, 2013)Polycrystalline ZnO thin film was obtained on the p-Si for the heterojunction diode fabrication by sol-gel method. X-ray diffraction study showed that the texture of the film is hexagonal with a strong (002) preferred ... -
Structural characterizations and optical properties of inse and inse:ag semiconductors grown by bridgman/stockbarger technique
Gürbulak, Bekir; Sata, Mehmet; Doğan, Seydi; Duman, Songül; Ashkhasi, Afsoun; Keşkenler, E. Fahri (Elsevier Science Bv, 2014)Undoped InSe and Ag doped InSe (InSe:Ag) single crystals have been grown by using the Bridgman/Stockbarger method. The freshly cleaved crystals have mirror-like surfaces even without using mechanical treatment. The structure ...
