Electronic Transport in Organic Materials: Comparison of Band Theory with Percolation/(Variable Range) Hopping Theory



original image

Band theory for inorganic materials versus hopping or percolation theory for organics? Band theory conduction is contrasted with the more widely used percolation and hopping theories for organic electronic materials (). These materials are generally of lower performance than their inorganic counterparts and this is often presented as justification for a different conduction mechanism. Here it is reasoned that switching to a different conduction mechanism for electronic organic materials is not justified.
