molecular-beam epitaxy

[mə′lek·yə·lər¦bēm ′ep·ə‚tak·sē] (solid-state physics) A technique of growing single crystals in which beams of atoms or molecules are made to strike a single-crystalline substrate in a vacuum, giving rise to crystals whose crystallographic orientation is related to that of the substrate. Abbreviated MBE.
