A Static Model for Electrolyte-Gated Organic Field-Effect Transistors Linköping University Post Print
... As reported [29], contact resistance in organic field effect transistors is highly dependent on gate voltage. To take this dependence into account, a power law dependence on VGT is given to the contact resistance in this form RC(V)=RC0VGT-(γ+1) [30], where RC0 is the contact resistance at VGT=1 V. H ...
