Resonant tunneling diodes: transport mechanism and circuit applications
In this paper we present a brief review of physical properties and proposed circuit applications of resonant tunnelling diodes, that, since their proposal in the seventies, have represented the prototypical nanoelectronic device .The paper follows the outline of the lecture given at the MIGAS summer school "Towards Nanoelectronics". We review the transport mechanism and stress the equivalence between the coherent and the sequential tunnelling models, if both models are properly extended. We then provide a brief review of digital and mixed signal applications, and the main references for the reader interested in an in-depth treatment of the discussed subjects.
