| Summary: | The temperature-dependent hysteresis-type transfer characteristics of pentacene-based organic thin film transistors (OTFTs) were researched. The temperature-dependent transfer characteristics exhibit hopping conduction behavior. The fitting data for the temperature-dependent off-to-on and on-to-off transfer characteristics of OTFTs demonstrate that the hopping distance (ah) and the barrier height for hopping (qϕt) control the carrier flow, resulting in the hysteresis-type transfer characteristics of OTFTs. The hopping model gives an explanation of the gate-swing hysteresis and the roles played by qϕt and ah.
