Polarization reversal in thin film lithium niobate on silicon
The spontaneous polarization of thin film LiNbO$\sb3$ has been shown to be reversible with the application of an electric field at room temperature. This electric field is applied across the sample in the form of a voltage ...
Band evolution and shell structure in large clusters: Aluminum(3-60)anion, copper(1-1113)anion, silver(1-58)anion, and gold(1-223)anion
Photoelectron spectroscopy of negatively, charged clusters of aluminum, copper, silver, and gold reveals electronic shell structure and electron energy band development. Photodetachment experiments on Au$\sb6\sp-$ also ...
Surface studies using spin-polarized electron energy loss spectroscopy
Spin-polarized electron energy loss spectroscopy (SPEELS) has been used to investigate several paramagnetic surfaces. In this technique, a low energy beam of spin-polarized electrons from a GaAs source is directed at the ...
Deposition, characterization, and applications of thin film lithium niobate
Ferroelectric thin films of lithium niobate have been epitaxially grown on a variety of silicon and gallium arsenide substrates by reactive r.f. sputtering. The deposition process was optimized by independently varying the ...
Theory of elastic x-ray resonant exchange scattering in lanthanides and actinides
Resonant X-ray scattering has been observed in lanthanides and actinides. The observed scattering is sensitive to magnetization, but it arises primarily from electric, rather than magnetic, multipole transitions. The ...
