تفاصيل الوثيقة نوع الوثيقة : مقال في مجلة دورية  عنوان الوثيقة : Nanocrystalline Cu2O/p-Si solar light-responsive Schottky photodiode Nanocrystalline Cu2O/p-Si solar light-responsive Schottky photodiode   الموضوع : physics  لغة الوثيقة : الانجليزية  المستخلص : Nanocrystalline of Cu2O thin film was synthesized by sol-gel spin-coating technique. The spectrophotometric characteristics of transmission and reflection were studied for the film deposited on glass substrate. The optical absorption measurements near the absorption edge indicate that the absorption mechanism is due to allowed direct transition with energy gap value of 2.09 eV. The currentvoltage characteristics of Al/Cu2O/p-Si/Al diode were studied under dark and various light intensities in the range 20-100 mW/cm(2). The main diode parameters such as barrier height, ideality factor, series resistance were calculated from the analysis of current-voltage characteristics and studied under various illumination intensities. Moreover, the results indicate that the diode has a high photoresponsivity and the photocurrent increases with increasing light intensity which supports the availability of the diode for photosensor applications. The capacitance and conductance characteristics indicate that the diode highly depends on both voltage and frequency. Higher increase in the capacitance under low frequency as well as the presence of a characteristic peak in the capacitancefrequency characteristics indicates the presence of interface states. Moreover, the stronger parameters of the diode performance such as series resistance and interface states were extracted from the capacitance-voltage-frequency and conductance-voltage-frequency characteristics.  ردمد : 0947-8396  اسم الدورية : APPLIED PHYSICS A-MATERIALS SCIENCE & PROCESSING  المجلد : 121  العدد : 1  سنة النشر : 1435 هـ 2015 م  نوع المقالة : مقالة علمية  تاريخ الاضافة على الموقع : Saturday, August 19, 2017  الباحثون اسم الباحث (عربي) اسم الباحث (انجليزي) نوع الباحث المرتبة العلمية البريد الالكتروني A.A Al-Ghamdi, Al-Ghamdi, A.A باحث رئيسي دكتوراه   A.A.M Farag Farag, A.A.M باحث مشارك دكتوراه   A.A.M Farag Farag, A.A.M باحث مشارك دكتوراه   A.A Hendi Hendi, A.A باحث مشارك دكتوراه   R.
