Comparison of N-doped ZnO and N-Al codoped ZnO thin films deposited by pulsed filtered cathodic vacuum arc deposition
Tuzemen, E. Senadim; Kara, K.; Takci, D. K.; Esen, R. (INDIAN ASSOC CULTIVATION SCIENCE, 2015)N-doped ZnO and N-Al codoped ZnO films are deposited onto glass substrate at room temperature by pulsed filtered cathodic vacuum arc deposition system. The films are characterized by X-ray diffraction, Raman spectra, ... -
Effects of Al concentration on photovoltaic property of ZnO:Al/p-type Si by pulsed filtered cathodic vacuum arc depositio ri system
Takci, D. K.; Tuzemen, E. Senadim; Yilmaz, S.; Esen, R. (NATL INST OPTOELECTRONICS, 2015)The effects of Al concentration on XPS, Raman, Hall and photovoltaic properties of Al-doped ZnO films were investigated onto Si (100) substrate by pulsed filtered cathodic vacuum arc deposition (PFCVAD) system, at room ... -
Modeling of reflectance properties of ZnO film using artificial neural networks
Yuksek, A. G.; Tuzemen, E. Senadim; Elagoz, S. (NATL INST OPTOELECTRONICS, 2015)A ZnO thin film was prepared on a p-Si (100) substrate by using a pulsed filtered cathodic vacuum arc deposition system (PFCVAD). Specular reflectance, a nondestructive technique, can be used to measure thickness, refractive ... -
Simulation of Highly Reflective GaN/AlxGa1-xN Distributed Bragg Reflector Structure for UV-Blue LEDs
Alaydin, B. O.; Altuntas, I.; Tuzemen, E. Senadim; Elagoz, S. (AMER SCIENTIFIC PUBLISHERS, 2018)In this study, we showed theoretically enhanced reflectance characteristics of nitride based blue Light Emitting Diode (LED) by adding GaN/AlxGa1-xN Distributed Bragg Reflector (DBR) between n-contact layer and GaN buffer ...
