Trap states as an explanation for the Meyer-Neldel rule in semiconductors

It is shown that whenever traps, distributed exponentially in energy, are governing the conduction in electrical materials, a Meyer-Neldel observation is expected. This is a direct result of the model incorporating a high density of traps by Shur and Hack. Since this type of conduction is common for low mobility materials, such as organic semiconductors or amorphous silicon, they are therefore likely to obey the Meyer-Neldel rule.
