Stability of a reflective coupling diode with the inclusion of thermal effects in narrow band-gap materials

Despite the difficulty in fabrication, resonant tunnelling diodes (RTD) have found a great deal of usage in the analogue, digital and mixed signal realms as a means of increasing the speed of signal processing circuitry, or in reducing the static power dissipation in the circuitry. Nevertheless, RTDs suffer from their non-planar structure. One possible solution is a planar diode, which operates via coupling of injected electron modes from an input waveguide to a corresponding output waveguide in a semiconductor hetrostructure, or a reflective coupling diode (RCD). In this paper, we investigate the role of temperature on the operation of an RCD.
