Abstract
The devices are fabricated with lightly doped silicon substrates, 19-A to 34-A gate oxide, $\sim$0.05-$\mu$um gate lithography, 100-A sidewall oxides, self-aligned PtSi, and no intentional doping. The thin gate and sidewall oxides enable high field emission currents at low voltages. These devices exhibit on-state currents of 200-400 $\mu$A/$\mu$m and on-off ratios of 20 to 50. Cryogenic refrigeration of the devices reduce the off-state leakage current by several orders of magnitude.
