We consider a trapping - detrapping noise model to explain the recently observed maximum in the spectral density of current fluctuations in organic semiconductors (tetracene, pentacene), under space-charge-limited-ctirrent conditions. The ratio u = n(t)/N(t) of filled to total traps is obtained from the current-voltage characteristics and is used to evaluate the current noise spectral density at the trap-filling transition.

Abstract
We consider a trapping - detrapping noise model to explain the recently observed maximum in the spectral density of current fluctuations in organic semiconductors (tetracene, pentacene), under space-charge-limited-ctirrent conditions. The ratio u = n(t)/N(t) of filled to total traps is obtained from the current-voltage characteristics and is used to evaluate the current noise spectral density at the trap-filling transition.Pubblicazioni consigliate
