Performance Evaluation of Double Gate Pentacene Organic FET Using Simulation Study

Comparative analysis between single gate organic FET and double gate is presented in terms of performance parameters such as ON-OFF current ratio, threshold voltage VTh, mobility μ, transconductance gm, output conductance g
