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?

Can you give a good journal for reference for hopping conduction in doped ZnO and also Le Bail and Pawley method determination of lattice parameters?

It's urgent. I need it very badly for my research. Please send those papers as attachment. Thanking you in anticipation.

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...

Is it necessary that to increase the bandgap together with the barrier height in substances like ZnO?

Generally in electrical studies of the sample like ZnO, with the increase in barrier height the conductivity decreases and thereby the bandgap increases in optical studies of the same sample. Is...
