Paper Abstract

The numerical analysis of the vacuum nanotriode model with three nanopillar field emifters is carried out. This analysis shows that fluctuation in transconductance of nanotriode can be explained with the assumption that three nanopillar field emitters are three sources of mutually coherent electron waves. The interference picture in the grid plane (in the gate aperture) varies depending on potential of a grid. Thereof the anode current of nanotriode oscillates. The transconductance dependence calculated on this model coincides with an experimental curve. It is shown that nanotriode with the opened aperture in the anode and with the second continuous anode-drain electrode at distances from 100 nanometers up to 1 mm from the first anode with an aperture will enable to demonstrate precise interference fluctuations in the current-voltage characteristic with amplitude on 2 orders more than in existing experiments. Such scheme of nanotriode will enable to receive the change of a sign on function in transconductance of nanotriode. In this case current-voltage characteristic of nanotriode will be N-shaped as in tunnel diode. This experiment will prove also that in the vacuum nanotriode the length of coherence of electrons in a tungsten wire of 2 nanometers in diameter at room temperature exceeds the sum of lengths of two lateral field emitters plus the distance between their bases (~5Onm).
