|---|
Organic static induction transistors (OSITs) with vertical structure have advantage of lower operational voltage compared to the organic field effect transistors with conventional lateral structure. In this study, OSITs based on pentacene films were applied to fabricate the organic inverters which can operate at low voltage. The experimental results demonstrate that organic inverters based on the OSITs show basic transfer characteristics and a low operational voltage of ±2 V.
Key Words: organic static induction transistor, pentacene, organic inverter, current on/off ratio, inverter transfer characteristic
