Autor: M.S. El-Bana, S.S. Fouad, H. Y. S. Al-Zahrani, I.M. El Radaf

Publikováno v: Ceramics International. 46:18778-18784

In this study, quaternary kesterite Cu2FeSnS4 (CFTS4) has been selected due to its interesting optical and electrical characteristics. The CFTS4 films were prepared by exploiting the chemical bath deposition process at room temperature. The films wer

Fabrication, Electrical and Photovoltaic Characterizations of SnSb2S4/n-Si Heterojunction

Autor: H. Y. S. Al-Zahrani, I.M. El Radaf

Publikováno v: Silicon. 13:1261-1267

An inexpensive spray pyrolysis technique was effectively used to form a p-type SnSb2S4 thin film on n-type Si wafer for the first time to produce SnSb2S4/n-Si heterojunction. The capacitance-voltage estimations of the SnSb2S4/n-Si heterojunction have

Novel synthesis, structural, linear and nonlinear optical properties of p-type kesterite nanosized Cu2MnGeS4 thin films

Autor: H. Y. S. Al-Zahrani, Ahmed Saeed Hassanien, I.M. El Radaf

Publikováno v: Journal of Materials Science: Materials in Electronics. 31:8336-8348

This study presents the preparation of novel Cu2MnGeS4 thin films deposited on glass substrates, for the first time by an inexpensive spray pyrolysis technique. The crystal structure of the Cu2MnGeS4 samples was checked via the X-ray diffraction tech

Non-linear piezoelectricity in wurtzite ZnO semiconductors

Autor: Max A. Migliorato, J. Pal, H. Y. S. Al-Zahrani

Publikováno v: Al-Zahrani, H Y S, Pal, J & Migliorato, M A 2013, ' Non-linear piezoelectricity in wurtzite ZnO semiconductors ', Nano Energy, vol. 2, no. 6, pp. 1214-1217 . https://doi.org/10.1016/j.nanoen.2013.05.005

In this work we explore the strain dependence of the piezoelectric effect in wurtzite ZnO crystals. We write the polarization in terms of the internal anion-cation displacement, the ionic and dipole charges and use ab initio Density Functional Theory

Beyond ZnO nanowires for piezotronics and nanogenerators

Autor: H-Y. Kim, Zheling Li, Max A. Migliorato, J. Pal, H. Y. S. Al-Zahrani, Omar M. Dawood, Robert J. Young, Mohamed Missous, James Sexton, U. Monteverde

Publikováno v: 2015 IEEE 15th International Conference on Nanotechnology (IEEE-NANO).

In the past decade ZnO nanowires have been the key enabling material for demonstrating novel electronics components in the field of piezotronics and in the first realization of a nanogenerator. What are the materials that will be crucial in demonstra

Publikováno v: AIP Conference Proceedings.

The piezoelectric effect in polar semiconductor has seen increased interest in recent years because of the prospect of exploiting semiconducting behavior and piezoelectric response, i.e. generating electric fields in response to pressure, in novel op
