Abstract

Current-voltage (J-V) and differential-conductivity-voltage (-V) characteristics are analytically calculated at zero temperature for a point contact consisting of: two Peierls conductors separated by an insulator (I). Here P is a conductor with charge density wave (CDW). The J-V and -V characteristics depend on the CDW phases in the mean field approximation. To calculate them analytically we assumed, where are the energy gaps of . The current J has a discontinuous jump at for . The differential conductivity has a singularity at for . The relation is obtained.
