Study of charge transfer mechanism and dielectric relaxation of all-inorganic perovskite CsSnCl3

The conduction mechanism in CsSnCl3 is interpreted through the following two approaches: the non-overlapping small polaron tunneling (NSPT) model (monoclinic phase) and the overlapping large polaron tunneling (OLPT) model (cubic phase).

Frequency stable dielectric constant with reduced dielectric loss of one-dimensional ZnO–ZnS heterostructures

ZnO–ZnS heterostructure is developed which shows frequency stable dielectric response at ≥103 Hz due to coupling of the bare charges in the form of overlapping large polaron and Zn2+–VO dipoles present at ZnO–ZnS heterostructure interface.

Large polaron formation and its effect on electron transport in hybrid perovskites

Many experiments have indicated that a large polaron may be formed in hybrid perovskites, and its existence is proposed to screen the carrier–carrier and carrier–defect scattering, thus contributing to the long lifetime of the carriers.
