Secondary ion mass spectroscopy measurements of heavily indium doped germanium samples revealed that a significant proportion of the indium dose is immobile. Using electronic structure calculations we address the possibility of indium clustering with point defects by predicting the stability of indium-vacancy clusters, In(n)V(m). We find that the formation of large clusters is energetically favorable, which can explain the immobility of the indium ions.
