TEMPERATURE INDEPENDENCE OF THE ANGLE-RESOLVED X-RAY PHOTOEMISSION SPECTRA OF GOLD AND PLATINUM VALENCE BANDS

PDF Version Also Available for Download.

Description

Angle-resolved valence-band x-ray photoemission spectra were taken along the [111] and [100] directions of gold single crystals and along the [100] direction of a platinum single crystal at room temperature (293K) and on a probe cooled nearly to liquid nitrogen temperature (77K). No change was detected on cooling the samples, in contrast to expectations based on a simple direct-transition model. A simple 'matrix-element' model appears to predict spectra well even at low temperatures, perhaps because the complexity of the high-energy final-state bands permits sampling effectively throughout the zone.
