Journal ArticleDOI
Nickel content effect on the microstructural, optical and electrical properties of p-type Mn3O4 sprayed thin films
TL;DR: In this article, the direct band gap energy exhibits a red shift from 2.23 to 1.87 eV with Ni doping, and the dependence of both σAC and s with temperature and frequency agrees well with the CBH model as suggested by Elliott.
Journal ArticleDOI

TL;DR: In this article, the mirage effect technique has been used to estimate the thermal conductivity of NiMn 2 O 4 ternary nickel manganese oxide thin films spinels.
Journal ArticleDOI
A study of optothermal and AC impedance properties of Cr-doped Mn3O4 sprayed thin films
TL;DR: In this paper, a Chrome-doped Mn{sub 3}O{sub 4} thin films were grown on the glass substrates by the spray pyrolysis technique at 350 °C.
