Optical conductivity

Optical conductivity

Optical conductivity is one of the powerful tools for studying the electronic states in materials.[1] If a system is subjected to an external electric field then, in general, a redistribution of charges occurs and currents are induced. For small enough fields, the induced polarization and the induced currents are proportional to the inducing field.
