Double exponential density of states and modified charge carrier transport in organic semiconductors

This paper discusses the use of an approximated charge carrier density to model organic thin-film transistor (OTFT) using a double exponential states. Traditionally, published work employs single states and Gaussian On contrary, this in Fermi integral evaluate for OTFT. We consider two states, one rateled tail region deep region, addition various associated parameters. The distribution localized trap between highest lowest orbital is expressed as Tail are better described by function, while Therefore, if we require that regions be defined then function should sum two, Gaussian, more accurately describe complete region. employed approximate mathematical methods, so error lower
