Abstract
The transport properties of the charge ordering compound $\beta - {\rm Na}_{\rm V}_{2}{\rm O}_{5}$ are studied in the temperature range from 65 K to 300 K using current driven DC conductivity experiments. Below the metal-insulator transition temperature (T $_{\rm MI} = 136$ K) this material shows a typical non-linear charge density wave behavior. The observed conductivity is discussed in terms of modified classical model for charge density wave transport, based on the domain structure of the charge ordered state.
