Optical Properties of Ordered As Layers on InP(110) Surfaces

Abstract
The structure of arsenic monolayers on InP(110) surfaces has been investigated by combining optical spectroscopy with calculations of the surface atomic structure and optical properties. A highly ordered surface structure is obtained after As deposition at room temperature followed by annealing at 300°C. From the excellent agreement between the experimental and theoretical results we conclude that the ordered structure consists of an InAs monolayer on the substrate surface.
