Low-Temperature Solution Route to Macroscopic Amounts of Hydrogen Terminated Silicon Nanoparticles

摘要

The production of hydrogen terminated silicon(Si)nanoparticles is currently an area of intense research.The primary methods of producing large amounts of hydrogen terminated Si is either from the mechanical fracturing of porous Si or the gas-phase decomposition of silane or organosilane gas.In both cases,further etching is necessary using nitric and hydrofluoric acid to produce a stable,well-passivated hydrogen surface.Once the surface is hydrogen passivated,further functionalization via hydrosilation is possible.This chemistry has been well-developed in the case of porous Si and opens the door for biological and technological applications,such as for quantum dot probes,optical and electronic applications,hydrogen storage,and solar energy.
