Abstract: Abstract Recent experimental studies have shown that metals at submicron scale may harden rather than soften after high temperature annealing, which is contrast to the typical behavior at macro level. In the present work, a… read more here.

Abstract: Relaxed Si1−xGex layers on Si(001) serve as virtual substrates for strained Si or Ge layers. However, plastically relaxed layers inevitably contain misfit and threading dislocations, negatively affecting devices. Deposition of a SiGe layer on the… read more here.
