“…Obviously, the low-temperature data of the amorphous sample can be extrapolated from the temperature region of the liquid phase, providing additional support for the interpretation of the amorphous phase as a frozen liquid. This has also been suggested on the basis of electron diffraction experiments on liquid and amorphous Au-Sn alloys, revealing almost identical static structure factors S(K) [7].…”

The solid-liquid-solid-phase transitions of a Au 50 Sn 50 alloy have been investigated by means of the recently developed method of time-resolved photoelectron spectroscopy, using dye laser pulses to melt the sample surface on a microsecond scale. Starting at a temperature of the liquid sample just above the melting point (740 K), the laser pulse heating allowed us to obtain, for the first time, valence band spectra of an alloy at temperatures of up to 1620 K, distinctly above the vapour pressure limit of steady-state photoelectron spectroscopy. The photoemission results of the liquid at different temperatures are compared with data from the corresponding amorphous alloy, prepared by vapour condensation at liquid-nitrogen temperature. By increasing the temperature of the disordered phase, the Au 5d band is found to shift continuously toward a lower binding energy, showing a linear behaviour over the whole temperature range. Our measurements confirm earlier results obtained with conventional photoemission within a restricted temperature range. The results presented here clearly show the potential of the new technique to investigate the electronic structure of alloys at conditions under which standard photoemission experiments cannot be performed.

“…However, disregarding this limitation, a-Na-Sn should behave similar to the noble-metal/polyvalent-metal systems like a-Cu-Sn [9,26], if we simply handle the system by assuming a valency of Z Na = 1 e/a for sodium. Because of the quite large diameter of Na, the expected particle density of a-Na-Sn should be much smaller, which is contrasted by n exp o , at least for x < 50 (Fig.…”
