Abstract
Structures including a compound-semiconductor-based device and a silicon-based device integrated on a semiconductor substrate and methods of forming such structures. The structure includes a first semiconductor layer having a top surface and a faceted surface that fully surrounds the top surface. The top surface has a first surface normal, and the faceted surface has a second surface normal that is inclined relative to the first surface normal. A layer stack that includes second semiconductor layers is positioned on the faceted surface of the first semiconductor layer. Each of the second semiconductor layers contains a compound semiconductor material. A silicon-based device is located on the top surface of the first semiconductor layer, and a compound-semiconductor-based device is located on the layer stack.
