Influence of in-situ annealing ambient on p-type conduction in dual ion beam sputtered Sb-doped ZnO thin films
Sushil Kumar Pandey,Saurabh Kumar Pandey,Vishnu Awasthi,Mukul Gupta,Uday P. Deshpande,Shaibal Mukherjee +5 more
TL;DR: Sb-doped ZnO (SZO) films were deposited on c-plane sapphire substrates by dual ion beam sputtering deposition system and subsequently annealed in-situ in vacuum and in various proportions of O2/(O2+n2)% from 0% (N2) to 100% (O2).
Journal ArticleDOI

Vivek Garg,Brajendra S. Sengar,Vishnu Awasthi,A. Kumar,Rohit Singh,Shailendra Kumar,C. Mukherjee,Victor V. Atuchin,Victor V. Atuchin,Shaibal Mukherjee +9 more
TL;DR: The use of DIBS-instigated plasmon-enhanced GZO can be a novel mean to improve the performance of photovoltaic, photodetector, and sensing devices.
Journal ArticleDOI
Band alignment of Cd-free (Zn, Mg)O layer with Cu2ZnSn(S,Se)4 and its effect on the photovoltaic properties
Brajendra S. Sengar,Vivek Garg,A. Kumar,Vishnu Awasthi,Shailendra Kumar,Victor V. Atuchin,Victor V. Atuchin,Shaibal Mukherjee +7 more
TL;DR: In this article, Cd-free n-type buffer layers with two different Mg-doped ZnO layers (Mg0.26Zn0.74O, Mg 0.30Zn 0.70O) have been examined using ultraviolet photoelectron spectroscopy.
Journal ArticleDOI
Effect of oxygen partial pressure on the behavior of dual ion beam sputtered ZnO thin films
Saurabh Kumar Pandey,Sushil Kumar Pandey,Uday P. Deshpande,Vishnu Awasthi,Ashish Kumar,Mukul Gupta,Shaibal Mukherjee +6 more
TL;DR: In this article, undoped ZnO thin films were grown on p-type Si substrates at different oxygen partial pressure by dual ion beam sputtering deposition system at a constant growth temperature of 400°C.
Journal ArticleDOI
