However, the electric conduction mechanism and the scaling properties underlying their performance differ significantly from those of conventional metal-oxide-semiconductor (MOS) field-effect transistors. Indeed, an understanding of channel length scaling and drain bias impact has not been elucidated sufficiently. Here, multiple ambipolar SB-FETs with different channel lengths have been fabricated on a single silicon nanowire ensuring a constant nanowire diameter. Their length scaling behavior is analyzed through drain current and transconductance contour maps, each depending on the drain and gate bias. The reduced gate control and extended drain field effect on Schottky junctions were observed in short channels. Activation energy measurements showed lower sensitive behavior of the Schottky barrier to gate bias in the short-channel device and confirmed the thinning of Schottky barrier width for electrons at the source interface with drain bias.
