Computer Simulation of Tunneling in Atomic-Size Devices
Electrons emitted from small atomic-size sources exhibit properties that differ substantially from those emitted by conventional sources. Experimental work on electron field emission from one and three-atom tungsten tips has shown that the low-energy electron beam is strongly focussed.1–4 Electron sources having these properties would be very valuable for applications to electron holography and electron interferometry.5–9
