Grating-coupled strain-enhanced light emission from mechanically stressed germanium nanomembranes

Direct-bandgap light emission from Ge nanomembranes is strongly enhanced and red-shifted through the application of tensile strain, combined with the use of a periodic array of amorphous-Si nanopillars to outcouple the strain-enhanced luminescence.
