摘要：

We measured field emission from a silicon nanopillar mechanically oscillating between two electrodes. The pillar has a height of about 200 nm and a diameter of 50 nm, allowing resonant mechanical excitations at radio frequencies. The tunnelling barriers for field emission are mechanically modulated via displacement of the gold island on top of the pillar. We present a rich frequency-dependent response of the emission current in the frequency range of 300 - 400 MHz at room temperature. Modified Fowler - Nordheim field emission is observed and attributed to the mechanical oscillations of the nanopillar.
