GaAs Spin Polarized Electron Source

April 1, 1980
Author(s)
Daniel T. Pierce, Robert Celotta, G Wang, W Unertl, A Galejs, C Kuyatt, S Mielczarek
The design, construction, operation, and performance of a spin polarized electron source utilizing photoemission from negative electron affinity (NEA) GaAs are presented in detail. A polarization of 43plus or minus}2% is produced using NEA GaAs (100). The

An Interface Phase Transition: Complete to Partial Wetting

March 7, 1980
Author(s)
Michael Moldover, John W. Cahn
When two fluid phases are near a critical point, one of them will be excluded from contact with any third phase that happens to be present by a wetting film of the other critical phase. A simple and quite general strategy that may be used to induce a phase

Ising Models for Order-Disorder Transition in an Adsorbed Overlayer

March 2, 1980
Author(s)
T M. Lu
Based on a 2D zero field anti-ferromagnetic Ising model, we obtain a relation between the angular distribution of intensity of a LEED superlattice beam from an adsorbed lattice gas with nearest-neighbor repulsive interaction and the spin-spin correlation

Ultraviolet Photoemission Spectroscopy of Pd-Si Glasses

February 1, 1980
Author(s)
B Waclawski, D S. Boudreaux
In order to determine systematic changes in the density of states with alloy composition, photoelectron spectra at hv=21.2 eV were measured for several amorphous alloys based on the well-known Pd-Si glass system. Three binary alloys with 15, 20, and 25 at
