R. Matzdorf et al., GIANT TEMPERATURE-DEPENDENCE IN ANGLE-RESOLVED ULTRAVIOLET-PHOTOEMISSION FROM AU(100), Surface science, 343(3), 1995, pp. 1182-1186
Angle-resolved photoelectron spectra from both the (1 x 1) and (5 x 20
) surfaces of Au(100) exhibit peak intensity variations by an order of
magnitude with changing polar angle of emission. We present experimen
tal evidence that the observed intensity modulation is caused by photo
electron diffraction and may be identified by an unusually strong depe
ndence on sample temperature.
