Thermionic generation generates electricity by collecting thermionic electrons emitted from the high temperature emitter with the opposite collector. When the distance between the emitter and the collector reduced to the nanoscale, in other words, the nanogap is used, thermionic generation can generates at room temperature due to quantum effects. However, there are few reports on the quantum effect between the nanogaps. In this study, we use MEMS device which can fabricate nanogaps by cleaving single-crystal silicon.
