Scanning Tunneling Microscopy Applied to Optical Surfaces

January 1, 1986
Author(s)
Robert A. Dragoset, R Young, Howard P. Layer, S Mielczarek, E C. Teague, Robert Celotta
The technique of scanning tunneling microscopy has been applied to topographic mapping of two optical surfaces: a ruled grating replica and a diamond-turned gold mirror. We have demonstrated the ability of the scanning tunneling microscope to measure

Author(s)
J H. Klote
The Veterans Administration (VA) has sponsored a project at the Center for Fire Research of the National Bureau of Standards to study smoke control in VA hospitals and evaluate design system approaches and methods of acceptance testing. This report

Spin Polarized Secondary Electrons: Theory

January 1, 1986
Author(s)
David R. Penn, S Apell, S Girvin
We show that the spin polarization of the secondary electrons, P(E), yields useful information about the electron-electron interaction. The ration of majority to minority spin lifetimes is related to the measured values of P(E) by τ uarr}(E)/τ darr} (E = [
