Abstract: Tetracene organic field-effect transistors (OFET) have been fabricated and investigated with La2O3 as gate insulator. The fabricated organic thin film transistors exhibit p-type conductivity with field effect mobility 1.04×10-4 cm2/V.s, ON-OFF ratio 3.465, sub-threshold swing 17.8 mV/decade and hole concentration 1.25×1019 cm-3. The SEM and XRD analysis on the semiconductor film were have also been reported.
