Ultra‐thin t‐Se nanoribbons are produced simply and conveniently via a vapor–liquid–solid (VLS) mechanism. The nanoribbons are highly crystalline and grow preferentially along the c‐axis, with an average thickness of 15 nm (see Figure) and lengths up to several hundreds of micrometers. The intermediates in the formation are series‐wound beads, which develop into 1D nanostructures confined by the anisotropic crystal structure of t‐Se during cooling.
