Abstract
AFM, STM and diffraction of He and H<sub>2</sub> have been used to assess Si(1 1 1)–H(1 × 1) surfaces for their potential as mirrors for matter-waves. The H-passivated samples are produced by wet-chemical methods and delivered to a different laboratory for diffraction measurements. We show that the surface is flat and homogenous over lateral scales of microns and that absolute He and H<sub>2</sub> reflectivities of the order of ∼3% are obtained, even after 20 h storage under Ar and several days storage in UHV. These characteristics allow the use of Si(1 1 1)–H(1 × 1) as a highly reflective mirror for atoms and molecules, with application in a future He microscope or focused hydrogen nano-lithography system.
