C-Au-S Semiconducting Layers for PVDF Ferroelectric Electron Emission

Electron emission phenomena from PVDF (polyvinylidene fluoride) ferroelectric substance by polarization inversion were studied. However the electron emission was not observed. To discussion the reason, the electric field distribution on the substance was theoretically calculated using a charge simulation method. The field was distributed along the surface of ferroelectric substance between the teeth electrodes. It was supposed that the high surface insulating properties prevented electron flow and accumulation on the surface. Therefore C-Au-S layer was tried to use as semiconducting layer on PVDF surface to accumulate the electric charge. The ability of C-Au-S layer on the ferroelectric electron emitter was discussed.
