The power device also includes a buffer layer coupled to the substantially single crystal layer and a channel region coupled to the buffer layer. The channel region comprises a first end, a second end, and a central portion disposed between the first end and the second end. The channel region also includes a channel region barrier layer coupled to the buffer layer. The power device further includes a source contact disposed at the first end of the channel region, a drain contact disposed at the second end of the channel region, and a gate contact coupled to the channel region.
