Mechanism of vertical Ge nanowire nucleation on Si (111) during subeutectic annealing and growth

open access: yes, 2011
The direct integration of Ge nanowires with silicon is of interest in multiple applications. In this work, we describe the growth of high-quality, vertically oriented Ge nanowires on Si (111) substrates utilizing a completely sub-Au-Si-eutectic annealing
