Using gold instead of more common dopants in these devices results in minority carrier suppression, lowering capacitance and enabling them to operate in high-frequency regimes.

In the Gunn type, the formation of dipole domains allows for the building of high-frequency microwave oscillators, and the Esaki type exhibit regions of operation with negative resistance due to quantum tunneling. Ideal ones are described by the Shockley equation, which gives the current flowing through one as an exponential function of the bias current, and avalanche ones work by causing a wave of ionization at a well- defined current. Also existing in Zener and Schottky forms, FTP, identify these circuit elements formed from a single PN junction and best known in their light-emitting incarnations.
