Magnetic anisotropy allows magnets to maintain their direction of magnetization over time. Using a scanning tunneling microscope to observe spin excitations, we determined the orientation and… (More)
We report an improved precision measurement of the Casimir force. The force is measured between a large Al coated sphere and flat plate using an Atomic Force Microscope. The primary experimental… (More)
We perform first-principles calculations of the surface and bulk wave functions of the Cu(111) surface and their hybridization energies to a Co adatom, including the potential scattering from the Co.… (More)

Effects of dopant segregation at the NiGe/Ge interface are analyzed theoretically and experimentally. First-principles calculations indicate that the physical Schottky barrier height would be reduced… (More)
