Activation Energy Analysis of Injection and Transport Processes in Organic Field-Effect Transistor

The temperature and voltage dependences of charge mobility and contact resistance is evaluated for the set of pentacene organic field-effect transistors. The activation energies of contact resistances (R_{c}) and R_{c} -free mobility are estimated to discuss origin of voltage dependence. The electri...

Description
Summary:	The temperature and voltage dependences of charge mobility and contact resistance is evaluated for the set of pentacene organic field-effect transistors. The activation energies of contact resistances (R_{c}) and R_{c} -free mobility are estimated to discuss origin of voltage dependence. The electric-field enhanced thermionic injection was found as a driving process of injection issue, whereas the Poole-Frenkel model rules the effective mobility.
