摘要

The linear-regime transfer properties of the annealed pentacene-based organic thin film transistors (OTFTs) in air at various temperatures up to 375 K are examined. It is found that the linear-regime carrier mobility increases with increasing annealing temperature reaching a maximum at 350 K, and then decreases with further increasing of annealing temperature beyond that point. However, an increase in annealing temperature leads to the shift of the threshold voltage towards positive gate-source voltages. An analysis through the temperature-dependent transfer characteristics of OTFTs reveals that the increased carrier mobility is the result of the reduced values of the hopping distance and the barrier height for hopping.
