Photosynthesis, which could control the size and position of Si nanocrystals being formed, as a novel nanofabrication technique making the best use of the strong interaction between photons and nanoparticles, is discussed in great detail. A nanocrystal growth is self-limited to the laser power and the laser-exposure time. The model is proposed to explain the self-limited growth and luminescence from...
Both photo-oxidation and photosynthesis manifest a strong interaction between nanoparticles and photons due to the large surface area-to-volume ratio. The final sizes of the semiconductor nanocrystals are determined by the photon energy during these phenomena. The photosynthesis is demonstrated in a Si-rich oxide and is similar to thermal synthesis, which involves the decomposition of SiO x ...
