Three types of nanostructured materials have been investigated: C60 on InP (100), Indium clusters on InP (100) and luminescent alkylated-Si quantum dots. The growth model and electronic structure of C60 molecules adsorbed on InP (100) were studied by XPS and UPS as a function of coverage and annealing temperature. The evolution of clean, In-terminated InP (100)-(2 x 4) surfaces is investigated by SRPES as a function of annealing temperature. During the course of illumination with 145 eV photons we have monitored the evolution of the Si 2p core level, and observed in real time a splitting and...
