Abstract

An avalanche increase of the drain current for high source-drain voltage (commonly called “kink effect”) has been observed for the first time in short-channel amorphous silicon thin-film transistors, fabricated using electron-beam lithography. This effect, caused by generation mechanisms at the drain junction, has been shown to be not only field but also temperature enhanced. The Frenkel-Poole mechanism is proposed in order to explain the data.
