Counterclockwise from top left: Illustration of SLS growth of Si nanowires (NWs). 5 mg of Si NWs settled out of a solution of chloroform. With light sonication the NWs are easily dispersed back into solution. SEM image of Si NWs synthesized using trisilane as a reactant and Bi nanocrystals (NCs) as seeds. HRTEM image of tip of Si NW seeded by Au NC.

HRTEM image of ~ 4 nm Bi NCs.
