... One possible method of creating a material with an effective bandgap of 1.6–1.8 eV using only group IV elements is to use β-SiC/Si superlattices. Many bilayers of very thin material (typically 20–60 bilayers of about 1–5 nm thickness) could be deposited or grown onto a silicon wafer, substantially m ...
