RT Journal Article SR Electronic T1 Strained-Layer Epitaxy of Germanium-Silicon Alloys JF Science JO Science FD American Association for the Advancement of Science SP 127 OP 131 DO 10.1126/science.230.4722.127 VO 230 IS 4722 A1 Bean, John C. YR 1985 UL http://science.sciencemag.org/content/230/4722/127.abstract AB Despite the dominant position of silicon in semiconductor electronics, its use is ultimately limited by its incompatibility with other semiconducting materials. Strained-layer epitaxy overcomes problems of crystallographic compatibility and produces high-quality heterostructures of germanium-silicon layers on silicon. This opens the door to a range of electronic and photonic devices that are based on bandstructure physics.
