Abstract
An electronic device including a substrate a group III-V layer on or above the substrate, wherein the III-V layer has an in-plane lattice constant that is greater than that of gallium nitride or wherein the III-V layer is at least partially relaxed; and an active region including a coherently strained group III-V channel layer on or above the III-V layer; wherein electron mobility in the channel layer is increased by the strain. Structures with an in-plane lattice constant that is smaller than that of gallium nitride are used for increasing the hole mobility by strain.
