Simple, Compact, High-Purity Cr Evaporator for UHV

September 1, 1993
Author(s)
Jabez J. McClelland, John Unguris, R E. Scholten, Daniel T. Pierce
A simple, compact Cr evaporator is constructed by electroplating Cr metal onto the tip of a W hairpin filament. At 5 cm from the evaporator, deposition rates up to 10 nm min -1 (flux {asymp} 10 19 atoms m -2s -1) have been obtained, with total deposition

Regimes of Surface Roughness Measurable with Light Scattering

January 1, 1993
Author(s)
Theodore V. Vorburger, Egon Marx, T Lettieri
In this paper we summarize a number of previous experiments on the measurement of the roughness of metallic surfaces by light scattering. We identify several regimes that permit measurement of different surface parameters and functions, and we establish

Spin-Polarized Photoemission Spectroscopy of Magnetic Surfaces Using Undulator Radiation

January 1, 1992
Author(s)
Philip Johnson, S Hulbert, R Klaffky, N Brookes, Andrew Clarke, B Sinkovic, N. Smith, Robert Celotta, Michael H. Kelley, Daniel T. Pierce, M Scheinfein, B Waclawski, B.O. Wells
A beamline has been established at the National Synchrotron Light Source to perform angle-resolved photoemission experiments on magnetic surfaces with spin sensitivity. The system has two novel features: it uses a miniature electron-spin polarization
