| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Vacuum transistors using field emitter array have been developed for a signal amplifier. We fabricated a gated 40,000-tip hafnium nitride field emitter array (HfN-FEA) and evaluated HfN-FEA as an active device. The vacuum transistor had a triode structure with a gated HfN-FEA and a collector electrode. The device exhibited a collector current of 1.1 mA, transconductance of 0.27 mS, collector resistance of 2.8 MΩ, and voltage amplification factor of 750 at the applying emitter voltage of -58 V. The vacuum transistor amplified ac signal, and voltage gain of 29 dB was obtained with a load resistance of 100 kΩ. The gain bandwidth product of 1 MHz was obtained. From the estimation of the equivalent circuit, gain bandwidth product of 36 MHz is expected with the vacuum transistor. | |
