Evolution and coarsening of Si-rich SiGe islands epitaxially grown at high temperatures on Si(001)
Morphology evolution of epitaxial SiGe on Si(001) islands grown at high temperature. We find that strong coalescence and coarsening effects dominate island growth. Under certain growth conditions remarkably uniform island ensembles can be created. We employ wet etching to trace the footprints of the island coarsening effects.
