Transport Properties of Nanostructured Organic Crystal of TTT(TCNQ)2

Abstract

The numerical modeling of electrical conductivity and thermopower of TTT(TCNQ)2 organic crystals is performed in order to investigate the prospect of using the mentioned crystals as thermoelectric material. The calculus is realized in the frame of three-dimensional (3D) physical model and the results are presented as function of Fermi energy for different degrees of the crystal purity. The influence of neighbor adjacent molecular chains on charge carrier transport is highlighted. The most effective methods to improve the thermoelectric efficiency are discussed.
