Semiconductor nanomembranes, extremely thin (<10 to ~1000 nm) single-crystal sheets, promise considerable new science and technology. They are flexible, they are readily transferable to other hosts and conform and bond easily, and they can take on a large range of shapes (tubes, spirals, ribbons, wires) via appropriate strain engineering and patterning. The ready ability to stack membranes allows the integration of the properties of different materials and/or orientations. A brief review of nanomembrane fabrication and manipulation with a view toward different types of applications is provided.
