Surface electronic properties by metastable deexcitation spectroscopy

Metastable deexcitation spectroscopy (MDS) is used to probe the surface electronic properties of semiconductor surfaces and different interfaces with semiconductors. Results are compared to photoemission data and calculations. The following case studies are treated: clean GaAs(1 1 0), clean Ge(1 1 1)c(2x8), Sb/GaAs(1 1 0), H:GaAs(1 1 0), Yb/GaAs(1 1 0), Yb/Si(1 0 0) and Ge(1 1 1) surface incomplete melting. For each system, MDS spectral features are related to surface valence band (VB) states
