Abstract
In this presentation, we will describe our results with field-emission type source and drain contacts in which the metal electrodes are tapered to a sharp point or an array of sharp points. The enhanced electric field as a consequence of this geometry results in more facile injection of charges from the metal to the band states of the semiconductor. The on-resistance of short channel TFTs is lowered and the channel lengths of TFTs can be reduced below 100 nm without adversely affecting the shape of the current-voltage characteristics.
