A novel high-current, high-resolution, low-kinetic-energy electron source for inverse photoemission spectroscopy
H. Ibach, H. Sato, M. Kubo +3
A high-current electron source for inverse photoemission spectroscopy (IPES) is described. The source comprises a thermal cathode electron emission system, an electrostatic deflect…
Electron energy loss spectroscopy with parallel readout of energy and momentum
Harald Ibach, François C. Bocquet, Jessica Sforzini +2
We introduce a high energy resolution electron source that matches the requirements for parallel readout of energy and momentum of modern hemispherical electron energy analyzers. T…
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…
Orientation Dependence of Step Stiffness: Failure of SOS and Ising Models to Describe Experimental Data
Sabine Dieluweit, Harald Ibach, Margret Giesen +1
We have investigated the step stiffness on Cu(001) surfaces as a function of step orientation by two independent methods at several temperatures near 300 K. Both sets of data agree…
