摘要：
A triode Pt nano electron source with a gate electrode to control the intensity of fringelike emission pattern with low gate voltage has been fabricated. Characteristics of the triode Pt nano electron source were measured at room temperature in a vacuum of less than 10(-7) Pa. The emission current was observed when the gate voltage was higher than 30V and showed a linear dependence in the Fowler-Nordheim plot. Electron wave interference patterns from the triode Pt nano electron source were first observed. The intensity of the electron wave interference pattern was successfully controlled by the gate voltage up to 50 V. (C) 2013 American Vacuum Society. [http://dx.doi.org/10.1116/1.4769976]
