Abstract

A III-N-based vertical transistor includes a III-N substrate, a source, a drain, and a channel comprising a III-N crystal material and extending between the source and the drain. The channel includes at least one sidewall surface aligned ±0.3° with respect to an m-plane of the III-N crystal material. The III-N-based vertical transistor also includes a gate electrically coupled to the at least one sidewall surface of the channel.
