WebMar 4, 2024 · The SiC epitaxial layers grown on 4° off-cut 4H-SiC substrate are the most common wafer type used today for a variety of device application. It is known that most of the defects are oriented parallel to the growth direction, therefore, epitaxial growth of SiC at an off-cut angle of 4° on SiC substrates not only preserves the underlying 4H-SiC ... WebMar 19, 2024 · Controllable growth of wafer-scale in-plane nanowires (NWs) is a prerequisite for achieving addressable and scalable NW-based quantum devices. Here, by introducing molecular beam epitaxy on patterned Si structures, we demonstrate the wafer-scale epitaxial growth of site-controlled in-plane Si, SiGe, and Ge/Si core/shell NW …

WebFor epitaxial growth the surface diffusion-incorporation time has to be less than one layer’s deposition time. This limits the technique to being a low temperature one. • Semiconductor and dopant sources are arrayed around the substrate. Each source and the substrate can be individually heated. Shutters control exposure to each species. •
