Bell Labs reports manmade single‐crystal monolayer alloys
DOI: 10.1063/1.3037407
A group at Bell Laboratories has reported making single‐crystal monolayer alloys of gallium arsenide and aluminum arsenide. This work could be the forerunner of a whole class of synthetic inorganic crystals that are identical in composition but distinct in structure and properties from naturally occurring compounds. Manmade superlattices, which consist of alternating layers of monocrystalline semiconductors, had been built at IBM and at Bell Labs earlier (
