Computation of Charged-Particle Transfer Maps for General Fields and Geometries Using Electromagnetic Boundary-Value Data
A. J. Dragt, P. Roberts, T. J. Stasevich +3
Three-dimensional field distributions from realistic beamline elements can be obtained only by measurement or by numerical solution of a boundary-value problem. In numerical charge…

Low-Temperature Orientation Dependence of Step Stiffness on {111} Surfaces
T. J. Stasevich, Hailu Gebremariam, T. L. Einstein +3
For hexagonal nets, descriptive of {111} fcc surfaces, we derive from combinatoric arguments a simple, low-temperature formula for the orientation dependence of the surface step li…

The Effects of Next-Nearest-Neighbor Interactions on the Orientation Dependence of Step Stiffness: Reconciling Theory with Experiment for Cu(001)
T. J. Stasevich, T. L. Einstein, R. K. P. Zia +3
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 ne…
