Mechanism of Conduction in Organic Semiconductors

A large number of investigations has been devoted to the mechanism of conduction in organic semiconductors.The first step in the study of the mechanism of conduction is generally the determination of n and µ appearing in the expression for conductivity σ = enµ. In inorganic semiconductors, this is done by measuring the Hall effect. Then, by studying the dependence of µ and n on the temperature and other parameters, the mechanism of conduction in the material investigated is deduced.
