Energy gap and pre‐exponential factor in dark conduction by organic semiconductors

Journal of Polymer Science Part C: Polymer Symposia, 1967
AbstractThe values of Δε and σ0 in the expression σ = σ0 exp {−Δε/2kT} for the dark conductivity σ, tend to increase together over the whole range of organic semiconductors. They fall into a broad band of values confined roughly between two lines given by log σ0 = αΔε + β, the compensation rule, with log σ0 varying from 5 ± 4 for Δε equal to 1.0 e.v ...

Some Thoughts and/or Questions about Activation Energy and Pre-Exponential Factor

Defect and Diffusion Forum, 2006
The first part of this paper presents a brief historical account of the Arrhenius law, starting from the seminal paper by Arrhenius (1889) up to theoretical developments mainly based on the rate theory. The second part describes the so called compensation rule (Meyer-Neldel rule), a correlation between activation enthalpy and entropy (or between pre ...
