FWP executive summaries: Basic energy sciences, materials sciences programs
Abstract
Research programs from Sandia Laboratory in Materials Science are briefly presented. Significant accomplishments include: preparation of Tl superconductors under equilibrium conditions; development of force-feedback sensor for interfacial force microscope; predictive model of hydrogen interactions in silicon dioxide on silicon; layer-by-layer sputtering of Si (001); oscillatory As4 surface reaction rates during molecular beam epitaxy of AlAs, GaAs, and InAs; and the effects of interfacial strain on the band offsets of lattice matched III-V semiconductor. Other accomplishments include: a new mechanism for surface diffusion; solid solution effects in Tl-containing superconductors; record high superconducting transitions for organic materials; atomic vibrations in boron carbides; and a method for studying radical/surface reactions in chemical vapor deposition (CVD).
