Density of states and extent of wave function: two crucial factors for
small polaron hopping conductivity in 1D    [PDF]

Margarita Dimakogianni, Constantinos Simserides, Georgios P. Triberis

We introduce a theoretical model to scrutinize the conductivity of small polarons in one-dimensional disordered systems, focusing on two crucial --as will be demonstrated-- factors: the density of states and the spatial extent of the wave function. The investigation is performed for any temperature up to 300 K and under electric field of arbitrary strength up to the polaron dissociation limit. To accomplish this task we combine analytical work with numerical calculations.
