Abstract:
1. A method for making a HEMT comprising: epitaxially growing a III-N based nanowire through a growth mask from a first portion of a doped buffer layer; forming a shell member surrounding a length of the III-N based nanowire for forming a two-dimensional electron gas (2-DEG) at an interface between the III-N based nanowire and the shell member, the shell member being disposed over a second portion of the doped buffer layer; forming a first dielectric layer surrounding a first portion of the shell member and over a third portion of the doped buffer layer; forming a metal gate surrounding a second portion of the shell member and over the first dielectric layer; and forming a second dielectric layer surrounding a third portion of the shell member and over a portion of the metal gate.
