Reversible electron pumping and negative differential resistance in two-step barrier diode under strong terahertz ac field
A computational study, employing a Floquet-transfer-matrix approach, of the current in a model two-step barrier diode under intense ac fields in the terahertz range is reported. It is demonstrated that the field pumps a net tunnel current through the structure, which can exhibit a negative different...
