Polarons in crystalline and non-crystalline materials
@article{Austin1969PolaronsIC, title={Polarons in crystalline and non-crystalline materials}, author={I. Austin and N. Mott}, journal={Advances in Physics}, year={1969}, volume={50}, pages={757 - 812} }
The current state of polaron theory as applicable to transition metal oxides is reviewed, including problems such as impurity conduction where disorder plays a role. An estimate is given of the conditions under which polaron formation leads to an enhancement of the mass but no hopping energy. The binding energy of a polaron to a donor or acceptor in narrow-band semiconductors is discussed. The experimental evidence about the conductivity of TiO 2 and NiO is reviewed. Impurity conduction in NiO… CONTINUE READING
