What are the sequential steps occurring in the supercritical fluid-liquid-solid growth method for synthesis of nanowires? Correct Answer Organometallic precursors are fed into the reactor ➔ Degradation of precursors ➔ Dissolution of silicon and germanium in metal nanocrystals ➔ Precipitation of solid crystallite ➔ Uniaxial growth of nanowires from nanocrystal seeds

Supercritical fluid liquid solid growth method is one of the solution phase techniques employed to synthesize semiconductor nanowires. In this technique metal nanocrystals are used as seeds whereas silicone or germanium organometallic substances are used as precursors. The precursors are introduced into the reactor filled with a super critical organic solvent like toluene. Thermolysis occurs leading to the degradation of the precursor and allowing their dissolution into the metal nanocrystals. A solid crystallite precipitates as more and more semiconductor solute is added from the supercritical phase. Thus, a nanowire grows uniaxially from the nanocrystal seed.
