Self-assembled single-crystalline Si1?xGex nanorings (NRs), as small as 10 nm with narrow distributions of height and diameter, have been fabricated without any specific equipment. Compared to other approaches for nanofabricating the ring-like structures, the smallest Si1?xGe x NRs with the highest density were obtained by the mediation of Au nanodots. The process promises the availability of Si1?xGe x NRs with a wide range of Ge concentration and size, and can serve as a useful platform for the fundamental understanding and future practical applications of NR devices.
