(e, 2e) spectrometer for investigating the spectral momentum density of thin-films
(AIP Publishing, 1984-08)An (e, 2e) spectrometer has been constructed for detecting scattered and recoiling electrons from a thin solid film. The cross section for observing the two electrons in coincidence is proportional to the spectral momentum ... -

Effect of multiple scattering on transition radiation from a dynamic interface
(American Physical Society, 1991-09)The effect of multiple scattering (long-range, small-angle elastic Coulomb collisions) on the radiation field associated with transition radiation from a nonstationary plasmalike medium is addressed with the help of a ... -
Effect of pressure on a defect-related band-resonant vibrational mode in implanation-disordered GaAs
(American Physical Society, 1994-10)We have used hydrostatic pressure as a means for studying a resonant Raman mode observed at 47 cm(-1) in highly disordered, ion implanted, unannealed GaAs. The mode shifts weakly (-0.07 +/- 0.15 cm(-1)/GPa), supporting an ... -
Effect of pressure on defect-related emission in heavily silicon-doped GaAs
(American Physical Society, 1994-11)We report cryogenic high-pressure measurements of a defect-related emission at 1.25 eV in silicon-doped GaAs. The pressure measurements prove that the 1.25-eV photon energy is relative to the conduction band, implying a ... -
Effect of the Magnus force on skyrmion relaxation dynamics
(Amer Physical Soc, 2018-01-10)We perform systematic Langevin molecular dynamics simulations of interacting skyrmions in thin films. The interplay between Magnus force, repulsive skyrmion-skyrmion interaction and thermal noise yields different regimes ... -
Effect of the minimal length uncertainty relation on the density of states and the cosmological constant problem
(American Physical Society, 2002-06-15)We investigate the effect of the minimal length uncertainty relation, motivated by perturbative string theory, on the density of states in momentum space. The relation is implemented through the modified commutation relation ... -

Effect of the size distribution of magnetic nanoparticles on metastability in magnetization relaxation
(American Physical Society, 2011-09-15)We theoretically examine metastability occurring in magnetization relaxation for magnetic nanoparticles with size distributions. An array ofmagnetic nanoparticles is simulated using a spin S = 1 ferromagnetic Blume-Capel ... -
Effects of anisotropic surface tension on first-order-transition singularities
(American Physical Society, 1985-02)For systems displaying two-phase coexistence without rotational invariance, anisotropic surface tension and nonspherical droplets are present. To study small fluctuations around such droplets, we construct a natural ... -
Effects of bonding type and interface geometry on coherent transport through the single-molecule magnet Mn-12
(American Physical Society, 2010-03)We examine theoretically coherent electron transport through the single-molecule magnet Mn-12, bridged between Au(111) electrodes, using the nonequilibrium Green's function method and the density-functional theory. We ... -
The effects of coating culture dishes with collagen on fibroblast cell shape and swirling pattern formation
(2020-09)Motile human-skin fibroblasts form macroscopic swirling patterns when grown to confluence on a culture dish. In this paper, we investigate the effect of coating the culture-dish surface with collagen on the resulting ... -
Effects of geometry and doping on the operation of molecular transistors
(AIP Publishing, 2003-03)We report first-principles calculations of current versus gate voltage characteristics of a molecular transistor with a phenyldithiolate molecule as active element. We show that (i) when the molecule is placed in proximity ... -
Effects of gravity on equilibrium crystal shapes: Droplets hung on a wall
(American Physical Society, 1987-04)General properties of equilibrium crystal shapes pinned on a vertical wall and subject to gravity are sought. For two-dimensional crystals, or three-dimensional ones with axial symmetry held in suitable geometries, we are ... -
Effects of next-nearest-neighbor interactions on the orientation dependence of step stiffness: Reconciling theory with experiment for Cu(001)
(American Physical Society, 2004-12)Within the solid-on-solid (SOS) approximation, we carry out a calculation of the orientational dependence of the step stiffness on a square lattice with nearest- and next-nearest-neighbor interactions. At low temperature ... -
Effects of receptor clustering on ligand dissociation kinetics: Theory and simulations
(CELL PRESS, 2005-12-01)Receptor-ligand binding is a critical first step in signal transduction and the duration of the interaction can impact signal generation. In mammalian cells, clustering of receptors may be facilitated by heterogeneous zones ... -

Effects of translational symmetry breaking induced by the boundaries in a driven diffusive system
(American Physical Society, 1991-04)We study the effects of the boundary conditions in a driven diffusive lattice-gas model which is known to display kinetic phase transitions. We find, in the case of attractive interaction, that a boundary-condition-induced ...
