Time-resolved electronic capture in germanium doped with hydrogen-like impurity centers [PDF]

open access: yes, 2012
The capture of free holes and electrons in germanium (Ge) doped by gallium (Ga) or antimony (Sb) has been studied by a time-resolved pump-probe experiment with the free-electron laser FELBE at the Helmholtz-Zentrum Dresden-Rossendorf.
