    Low-Threshold Field Emission from Carbon Structures

    The surface of graphene-like structures placed in an electric field with a strength of 1−10 V/μm is found to undergo considerable deformation. This effect is observed in both a direct field (emission current i...

    Low-Threshold Field Electron Emission from Two-Dimensional Carbon Structures

    Particles of multilayer graphene obtained by the method of self-propagating high-temperature synthesis are proposed as an active cathode component for field electron emission. It is shown that this material ma...

    New Type of the Electron Emission Induced by the Electric Field

    A new type of the electron emission induced by a pulsed electric field with a strength of about 105 V/cm applied to the cathode made of graphene-like structures has been found. Pulsed currents of up to several...

    Peculiarities of the total energy distribution of field emission electrons from graphene-like structures

    It is demonstrated that the field emission from graphene-like structures (GLSs) has a very low excitation threshold (about two orders of magnitude lower than that of metals and semiconductors). It is shown tha...

    Low-threshold field electron emission from carbon nanoclusters formed upon cold destruction of graphite

    The field-emission characteristics of carbon nanoclusters (graphenes, nanotubes, their compositions with microdiamonds) produced by the cold destruction of natural graphite are studied. The structure of a coat...
