(solid-state physics)
An electron in a crystal lattice together with the surrounding lattice deformation, for the case in which the deformation extends over many lattice sites so that the lattice can be treated as a continuum.

Hence, various theoretical conductivity models were adopted such as electron tunneling (ET), correlated barrier hopping (CBH), small and large polaron tunneling (SPT and LPT) models.
Overlapping large polaron tunnelling (OLPT) model: In the OLPT model, the exponent s is temperature dependent.
The polaron hopping mechanism is dominant in the sample, and a transition from large polaron to small polaron hopping takes place in the sample.
