Can anyone explain why the AC conductivity initially decreases on doping and then increases on further doping in ZnO?

The ac conductivity decreases on 1 wt % doping than the undoped one. But when it is increased to 3 wt %, it increases more than the undoped one. Can anyone give the explanation or reference?

What are the applications of doped ZnO in the mid-frequency range?

The frequency range is 100 Hz to 100 kHz. The doping on ZnO has been done with Cu, Cd and Ru. In come cases ac conductivity increases with doping and in certain cases ac conductivity decreases...

Can anyone explain why the AC conductivity initially decreases on doping and then increases on further doping?

I have found that the AC conductivity initially decreases on doping (1 at wt %) below the undoped value and then on further doping (3 at wt %) it increases more than the undoped one in case of Cd...
