Polarization Pendellösung and the Generation of Circularly Polarized X Rays with a Quarter-Wave Plate
(American Physical Society (APS), 1986)
A continuously tunable x-ray compensator that works in conjunction with synchrotron-radiation sources has been developed. The phenomena of polarization Pendellösung has been observed during its normal operation and the ...
Normal Displacements on a Reconstructed Silicon (111) Surface: An X-Ray-Standing-Wave Study
(American Physical Society (APS), 1986)
The average relaxation of the top layers of a germanium-atom-tagged Si(111) surface has been measured by x-ray interferometric and fluorescence methods. The results indicate a slight outward displacement (∼2%) of the outer ...
New Reconstructions on Silicon (111) Surfaces
(American Physical Society (APS), 1986)
We report the first observation of a class of new reconstructions on clean silicon (111) surfaces. The surfaces are prepared by a combination of laser and thermal annealing and the new structures are studied with a tunneling ...
