Theoretical studies of catalytic conversion in a flow reactor reveal that a compensation effect will be observed under certain restrictive conditions. It appears that the compensation effect is observed when two or more coupled transport processes are involved and consequently may be a general law. Compensation effects have been observed in electronic conductivity in semiconductors, diffusion of atoms in solids, etc however, more work is needed to establish its generality.

There are, however, many systems showing anomalous fast diffusion, where metallic impurities such as Fe, Ni, Co, Cu, and Au in titanium, scandium, alkali, IVB group metals and semiconductors diffuse several orders of magnitudes faster than their self-diffusion in these materials, although the atomic sizes of the... 

Due to the low mobility in organic semiconductors, diffusion transport is also very important for the charge injection process. Therefore, an analytical diffusion controlled charge injection model particularly suited for OLEDs has been developed [33]. This model is based on drift-diffusion and multiple trapping theory. The latter can also be used to describe hopping transport in organic semiconductors [34],...
