Reconstruction of the diamond (1 1 1) surface

Dissociation of {1 1 1} faces into {1 1 0} faces in thick diamond films

Surface morphology of thick diamond films was investigated using scanning electron microscopy (SEM). The dissociation of [1 1 1} faces into {1 1 0} faces is positively confirmed by the geometrical consideration of the crystal shapes, such as the V-shaped penetration twins and some other unusual crystal shapes. Growth mechanisms of the diamond rLl 1 1} and {1 1 O} faces are discussed. PACS: 81.0...

Cohomology of aff(1|1) acting on the space of bilinear differential operators on the superspace IR1|1

We consider the aff(1)-module structure on the spaces of bilinear differential operators acting on the spaces of weighted densities. We compute the first differential cohomology of the Lie superalgebra aff(1) with coefficients in space Dλ,ν;µ of bilinear differential operators acting on weighted densities. We study also the super analogue of this problem getting the same results.

THE ACTIVATION OF CARBON DIOXIDE AT A MAGNESIUM (1 00) SURFACE THE ROLE OF OXYGEN TRANSIENTS

X-ray photoelectron and high resolution electron energy loss spectroscopic (XPS-HREELS) studies have shown that the adsorption of carbon dioxide at Mg(100) surfaces at 80K is followed by a dissociative reaction leading to the formation of a metastable surface carbonate above 80K. The formation of a carbonate species is proposed to proceed through oxidation of C0 (g) by an active oxygen su...
