The values of barrier height and ideality factor for n-ZnO/p-GaAs heterojunction diode were determined to be 0.61 eV and 1.83, respectively. The I-V characteristics of the heterojunction diode exhibit a non-ideal behavior. The ideality factor which is greater than unity was attributed to the series resistance, interface states and interfacial layer. The modified Norde's function combined with conventional forward I-V method was used to obtain the parameters including the series resistance and barrier height (BH). The capacitance-voltage (C-V) measurements were performed in the range of 100 kHz to 1 MHz. The interface distribution profile (D-it) as a function of bias voltage was extracted from the C-V and G(adj)-V characteristics. The interface state density of n-ZnO/p-GaAs diode is of the order of 10(13) eV(-1) cm(-2). Also, the I-V characteristics of n-ZnO/p-GaAs heterojunction diode were investigated in the temperature range of 293-393 K.  ISSN : 1386-9477  Journal Name : PHYSICA E-LOW-DIMENSIONAL SYSTEMS & NANOSTRUCTURES  Volume : 64  Issue Number : 11  Publishing Year : 1435 AH 2014 AD  Article Type : Article  Added Date : Thursday, July 27, 2017  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email M Soylu Soylu, M Investigator Doctorate soylum74@yahoo.com A.A Al-Ghamdi, Al-Ghamdi, A.A Researcher Doctorate   Omar A Al-Hartomy Al-Hartomy, Omar A Researcher Doctorate   Farid El-Tantawy El-Tantawy, Farid Researcher Doctorate   F Yakuphanoglu Yakuphanoglu, F Researcher Doctorate   Files File Name Type Description  42304.pdf pdf   Back To Researches Page
