Structures and devices, and methods of making such structures and devices, including a gate dielectric layer are provided. A semiconductor structure can include a semiconductor channel layer including a nitride-free semiconductor layer and a gate dielectric layer including a group III-nitride layer, wherein the gate dielectric layer is disposed over the semiconductor channel layer. A method of making a semiconductor device structure is also provided. The method includes providing a semiconductor channel layer including a nitride-free semiconductor layer and providing a gate dielectric layer including a group III-nitride layer, wherein the gate dielectric layer is disposed over the semiconductor channel layer. A metal-insulator-semiconductor field effect transistor (MISFIT) device structure can include a semiconductor channel layer including a nitride-free semiconductor layer and a gate dielectric layer comprising a group III-nitride layer, wherein the gate dielectric layer is disposed over the semiconductor channel layer. The MISFIT may include a gate electrode disposed over the gate dielectric. The MISFIT may include a source and drain region separated by the semiconductor channel layer.
