Abstract:
Monolayers of Dy and Ho deposited on Si(111)7 à 7 surfaces and annealed at T > 600°C convert into epitaxial pseudo-disilicide interfaces which are terminated by extra silicon at the surface. Extended and core electron states are probed by synchrotron radiation photoemission and provide a chemical characterisation of there two-dimensional interfaces which have been recently found to display a very strong dichroism in X-ray absorption studies.
