Abstract :
Micromachined opposing sharp silicon tips with spacing of 100 nm were fabricated using anisotropic etching. Field emission between the tips was performed with in-situ observation of the tips using a transmission electron microscope (TEM). Anode tip shape deformation in the few nanometer region was observed at high current density, while the cathode remain unchanged. The mechanism of energy exchange is explained using a field emission cooling mechanism.
