|Title:||Two-step Barrier Diodes|
Goncalves Da Silva C.E.T.
|Abstract:||Transmission probabilities and current densities of a two-step barrier heterostructure are calculated within the effective-mass approximation as a function of electron energy and applied bias. This system shows negative differential resistance under forward bias, because of a quasibound state in a triangular well, and no resonance under reverse bias, in the current density. The two-step barrier diode may show negative resistance in an ac field in the absence of a dc bias.|
