Research Abstract |
Development of beam deposited Pt field emitters for electron wave interference and in-situ observations of the electron emission sites of these emitters were investigated. These results indicated that the electron wave interference is generated by electrons emitted from two adjacent emission sites within a Pt nanocrystal. Further, in-situ transmission electron microscopy observations of the Pt field emitter during field emission and field evaporation were investigated. The Pt nanocrystals were found to move to the top of Pt field emitter during field evaporation. These results show the possibility of the control of electron emission sites in atomic scale by field evaporation.
