Journal ArticleDOI
Microstructural, optical and electrical properties of Cr-doped ZnO
TL;DR: In this article, a network of petal-like structures found to be unique to Cr-doped ZnO polycrystalline samples were synthesized chemically and optical measurements confirmed the presence of Cr in the lattice.
Journal ArticleDOI
Oxygen vacancy controlled tunable magnetic and electrical transport properties of (Li, Ni)-codoped ZnO thin films
TL;DR: In this article, the electrical, magnetic, and magnetotransport properties of Li-Ni codoped ZnO thin films in the electron dominated, hole dominated, and insulating regimes were investigated.
Journal ArticleDOI
Structural transition and blue emission in textured and highly transparent spray deposited Li doped WO3 thin films
M. Kovendhan,D. Paul Joseph,E. Senthil Kumar,A. Sendilkumar,P. Manimuthu,Sangaraju Sambasivam,C. Venkateswaran,R. Mohan +7 more
TL;DR: In this paper, the effect of Li doping on the properties of WO 3 thin films deposited using an automated homemade spray pyrolysis unit is studied. And the results reveal that the transparency of the Li-doped films is much greater than that of undoped film.
Journal ArticleDOI
A codoping route to realize low resistive and stable p-type conduction in (Li, Ni):ZnO thin films grown by pulsed laser deposition.
TL;DR: XPS measurements reveal that most favorable chemical state of Ni is Ni(3+) in (Li, Ni): ZnO, and it is argued that these Ni( 3+) ions act as reactive donors and increase the Li solubility limit.
Journal ArticleDOI
EXAFS and XANES investigation of (Li, Ni) codoped ZnO thin films grown by pulsed laser deposition
Lorenzo Mino,Diego Gianolio,Fabrizio Bardelli,Carmelo Prestipino,E. Senthil Kumar,F. Bellarmine,M. Ramanjaneyulu,Carlo Lamberti,M. S. Ramachandra Rao +8 more
TL;DR: Preliminary investigations on the Zn K-edge of the undoped and doped ZnO thin films revealed that doping has not influenced the average Zn-Zn bond length and Debye-Waller factor, which shows that both Ni and Li doping do not appreciably affect the average local environment of Zn.
