Field electron emission characteristic of graphene

Field Emission Microscopy, Spectroscopy,Scanning Electron Microscopy and Field Emission Phenomena from Graphene-like Structures

The presented paper gives a general overview of studies of field emission from carbon nanoclusters. The special attention has been given to the study of emission processes in the strong and super strong electric fields from graphene-like structures. The direct experiments have confirmed the phenomena of the low threshold field emission and explosive emission from carbon nanoclusters. Experiment...

Emittance of a field emission electron source

An analytical formula of the emittance of a field emitter is given. In contrast to thermal and photoemission, such a formula contains complexity due to the multidimensional nature of the source. A formulation of emittance is given for oneand three-dimensional 3D field emitters. The 3D formulation makes use of the point charge model of a unit cell emitter coupled with a trajectory analysis to fo...

Laser-induced ultrafast electron emission from a field emission tip

We show that a fi eld emission tip electron source that is triggered with a femtosecond laser pulse can generate electron pulses shorter than the laser pulse duration (100  fs). The emission process is sensitive to a power law of the laser intensity, which supports an emission mechanism based on multiphoton absorption followed by over-the-barrier emission. Observed continuous transitions betw...
