Abstract

Impact of the depth of a quantum barrier in the form of a tunnel-thin charge-depletion carbon layer in the enriched noncrystalline carbon template on non-dissipative transport and field electron emission has been studied. It has been shown that cross-current nonlinearities in current variables in heterostructures with static low-field electric effects and current-voltage curve parameters of the field electron emission in the strong pulse electric fields with microsecond duration are determined by the parameters of quantum barrier and by the implementation of resonant tunneling conditions with different zero levels of size quantization energy.
