The Ge(1 1 1)3d threshold has been studied near the 1050 K surface order-disorder transition by using Electron Energy Loss Spectroscopy (EELS). In the same temperature range in which the structural transition occurs, a sharp change in the lineshape is observed.

Abstract
The Ge(1 1 1)3d threshold has been studied near the 1050 K surface order-disorder transition by using Electron Energy Loss Spectroscopy (EELS). In the same temperature range in which the structural transition occurs, a sharp change in the lineshape is observed. The comparison with the EELS spectra of the 3d threshold measured on liquid and amorphous germanium favours the hypothesis of an amorphous-like surface layer.File in questo prodotto:
