Depth dependence of the ionization energy of shallow hydrogen states in ZnO and CdS
Depth dependence of the ionization energy of shallow hydrogen states in ZnO and CdS
The characteristics of shallow hydrogen-like muonium (Mu) states in nominally undoped ZnO and CdS (0001) crystals have been studied close to the surface at depths in the range of 10 nm - 180 nm by using low-energy muons, and in the bulk using conventional muSR. The muon implantation depths are …
