Abstract :
A diamond field emission triode with very low gate turn-on voltage of 10 V and high gain factor of 250 is reported. The gated diamond triode was fabricated with a self-aligning gate technique on a silicon-on-insulator (SOI) wafer. The Ia-Vg plot of emission characteristics with 4 tips shows a very low gate turn-on voltage of 10 V and high emission current of 6 μA at gate voltage of 20 V. Ia-Va plots of emission characteristics demonstrate the desired saturation behavior of a field emission transistor with a high voltage gain of 250. The low turn-on gate voltage and high gain factor is comparable to solid-state devices, confirming that the diamond field emission triode has significant potential for IC-compatible vacuum microelectronic applications and beyond
