ABSTRACT
The feasibility of Gunn oscillations in a planar nanoscale unipolar diode or a self-switching device (SSD) is analyzed using Monte Carlo simulations. The asymmetric nanochannel that the SSD is based on is shown to induce charge domains much more receptively when compared to a reference symmetric nanochannel. The oscillation frequency reaches 130 GHz. Potential applications are discussed in terms of the ease of heat dissipation and generation of oscillations at different frequencies on a single chip, in contrast to a conventional vertical-structure Gunn diode.
