Oxidation state, local structure distortion, and defect structure analysis of Cu doped α-MnO correlated to conductivity and dielectric properties.

Cu-doped MnO with the composition of MnCuO (x = 0-0.15) was synthesized and characterized. The synthesis was carried out by hydrothermal method at 140 °C for 5 h of reaction dwell time.

The effects of Fe-doping on MnO: phase transitions, defect structures and its influence on electrical properties.

The composition of Mn Fe O ( = 0-0.15) was synthesized by a hydrothermal method at 140 °C for 5 hours of reaction time. Investigations were carried out including XRD, FTIR, Raman spectroscopy, FESEM, and TEM for crystallographic phase analysis.
