Surface Preparation of InAs (110) Using Atomic Hydrogen

Atomic Structure and Energetic Stability of the Bi–covered InAs(110) Surface

We have performed ab initio calculations of the atomic structure and energetic stability of the Bi–covered InAs(110) surface. The calculations were performed within the density–functional theory, using norm– conserving fully separable ab initio pseudopotentials. Two experimentally proposed structural models have been considered: (1×1)–ECLS and (1×2). Our total energy calculations indicate that ...

Hydrogen-Induced Polymorphism of the Pd(110) Surface

Using density functional theory, we investigate the adsorption of hydrogen on Pd(110). We find this system to be unique in that hydrogen modifies the surface morphology into a multitude of coexisting structures, which are precursors for its solution in the bulk metal. This behavior is manifested in the energetic near degeneracy between the s1 3 2d paired-row and missing-row structures, and s2 3...

Epitaxial graphene surface preparation for atomic layer deposition of Al2O3

Atomic layer deposition was employed to deposit relatively thick ( 30 nm) aluminum oxide (Al2O3) using trimethylaluminum and triply-distilled H2O precursors onto epitaxial graphene grown on the Si-face of silicon carbide. Ex situ surface conditioning by a simple wet chemistry treatment was used to render the otherwise chemically inert graphene surface more amenable to dielectric deposition. The...
