Abstract: Pentacene OTFTs have been successfully reported using Pr2O3 as a gate insulator. The use of high dielectric constant gate dielectric reduces the threshold voltage of the OTFTs bellow-1V. The technique high temperature O2 annealing is success fully used to improve the surface geometry of Pr2O3 films. The fabricated OTFTs gives very low threshold voltage-0.8V and sub-threshold swing 0.9V/decade. The calculated ON-OFF ratio is 1.2x104 and mobility is 0.043cm2/V.s. |
