Abstract
It is established by direct experiments that the main component of the stationary field-emission current in fields E5 V/cm is due to piezogeometric intensification (by a factor of 103) of the electricfield at the end faces of piezoelectrically active films. An emission mechanism governed by electrons supplied by tunneling from the valence band of the piezoelectric is proposed.Keywords
