Po. Nilsson et al., ELECTRONIC-STRUCTURE OF BURIED SI LAYERS IN GAAS(001) AS STUDIED BY SOFT-X-RAY EMISSION, Physical review. B, Condensed matter, 52(12), 1995, pp. 8643-8645
It is demonstrated that it is possible to investigate details of the e
lectronic structure of an internal atomic monolayer using soft-x-ray-e
mission spectroscopy. The local and partial density of states of one m
onolayer and three monolayers of Si, embedded deep below a GaAs(001) s
urface, was extracted. Clear differences to the density of states for
bulk Si were observed.
