Abstract: is a strong topological insulator (TI)with a single Dirac cone and chiral spin texture[1, 2]. Surface-sensitive probes have directly ac-cessed the topological surface states, but trans-port measurements have proven dicult due tobulk contributions to the conductivity [3, 4]. Ef-forts aimed at isolating surface transport proper-ties have focused on mechanical exfoliation, elec-trical gating, and chemical doping [5{9]. An al-ternative way to minimize bulk contributions tothe conductivity is to synthesize nanostructureswith a large surface-to-volume ratio [10, 11]. Wedemonstrate the controlled synthesis of Bi
