A vapor–liquid–solid method for the growth of single‐crystalline (Bi 1− x Sb x ) 2 Te 3 nanowires with adjustable Bi–Sb mixing ratios is presented. Thermoelectric measurements on individual nanowires indicate a significant contribution from topological surface states to the total transport over the entire chemical composition range.
