    摘要: Various heterostructures and methods of forming heterostructures are disclosed. A method includes removing portions of a substrate to form a temporary fin protruding above the substrate, forming a dielectric material over the substrate and over the temporary fin, removing the temporary fin to form a trench in the dielectric material, the trench exposing a portion of a first crystalline material of the substrate, forming a template material at least partially in the trench, the template material being a second crystalline material that is lattice mismatched to the first crystalline material, forming a barrier material over the template material, the barrier material being a third crystalline material, forming a device material over the barrier material, the device material being a fourth crystalline material, forming a gate stack over the device material, and forming a first source/drain region and a second source/drain region in the device material.
