High-quality single-crystal Ge nanomembranes are fabricated from Ge-on-insulator substrates by etching the buried oxide to release the Ge template layer. Once transferred onto a flexible substrate, these ultrathin membranes can be highly strained, leading to the formation of (quasi-)direct-bandgap Ge with highly enhanced radiative efficiency. These strained nanomembranes are promising for the development of group-IV semiconductor lasers emitting in the technologically important 2–2.5 μm mid-infrared spectral region.
