文摘
- •
Temperature-dependent electrical conductivity is studied for AC–MO nanocomposites.
- •
Nanocomposites are prepared by wet impregnation and heating at 200 or 850 °C.
- •
The decrease in conductivity for the nanocomposites depends on several factors.
- •
AC and all the nanocomposites behave as extrinsic semiconductors.
- •
Supported MO nanoparticles introduce trap energy levels along the band gap of AC.
