• Dissipation through spin Coulomb drag in electronic spin transport and optical excitations 

    D'Amico, Irene; Ullrich, Carsten A. (American Physical Society, 2006-09)
    Spin Coulomb drag (SCD) constitutes an intrinsic source of dissipation for spin currents in metals and semiconductors. We discuss the power loss due to SCD in potential spintronics devices and analyze in detail the associated ...
  • An investigation of nonlinear tip-sample force models for nanoindentation 

    Hazra, Siddharth (University of Missouri--Columbia, 2007)
    Current physical models of tip-sample interactions in nanoindentation and atomic force microscopy are exclusively based on either the Johnson-Kendall-Roberts (JKR) or Derjaguin-Muller-Toporov (DMT) models of adhesive contact ...
  • Lorentz shear modulus of a two-dimensional electron gas at high magnetic field 

    Tokatly, I. V.; Vignale, Giovanni, 1957- (American Physical Society, 2007-10)
    We show that the Lorentz shear modulus—one of the three elastic moduli of a homogeneous electron gas in a magnetic field—can be calculated exactly in the limit of high magnetic field (i.e., in the lowest Landau level) and ...
  • Nanomechanical property characterization of femoral head materials 

    Tirunagari, Prashanthi (University of Missouri--Columbia, 2006)
    Orthopedic Implants under long-term physiological loading could produce changes in the surface mechanical properties and possible failure. The knowledge of mechanical properties and improving the wear resistance of these ...
