Boron doped graphene based linear dynamic range photodiode
Dere, A.; Coşkun, Burhan; Tataroğlu, A.; Al-Sehemi, Abdullah G.; Al-Ghamdi, Ahmed A.; Alateeq, Hind M. A.; Yakuphanoğlu, F. (Elsevier Science Bv, 2018)The boron-doped graphene oxide film was prepared using drop casting/coating technique. The film was coated by hydrothermal method on p-Si substrate and thus Al/p-Si/B-doped GO/Au diode was fabricated. The structural ... -
Optoelectronic investigation of Cu2FeSnS4 quaternary functional photodiodes with IR detection capabilities
Koç, Mümin Mehmet; Dere, Ayşegül; Özdere, Alper; Al-Sehemi, Abdullah G.; Coşkun, Burhan; Al-Ghamdi, Ahmed A.; Yakuphanoğlu, Fahrettin (Elsevier, 2021)Cu2FeSnS4 semiconductor used in the preparation of quaternary photodiodes was synthesized using hydrothermal synthesis. The nanoparticles were then spin coated on a silicon substrate. Nanoparticles were characterized using ... -
The The validity of Kohlrausch law for the photocurrent transient and the role of N-2/Ar flow ratio in photoconductivity of sputtered CoZnO
Soylu, M.; Coşkun, Burhan; Al-Sehemi, Abdullah G.; Al-Ghamdi, Ahmed A.; Yakuphanoğlu, Fahrettin (Elsevier Science Sa, 2017)Co:ZnO (CZnO) ferromagnetic semiconductor layers are coated on the surface of glass and Si substrates by Magnetron Sputter Deposition Method (MSDM) with variable N-2/Ar gas flow ratio. N-2/Ar flow ratio varies from 5 sccm ...
