What is Nano silicon?
Nano silicon
The smallest diameter of crystal silicon particles is 5 nanometers. Nano silicon powder is high in purity and has small particles. It also has uniform distribution. This product is tasteless and non-toxic thanks to its high surface area, high activity and low bulk density. Nano silicon powder, a new generation optoelectronic materials, is a high-power source material and has a wide gap energie semiconductor.
Nano silicon research is undergoing new developments
(1) Change the amount of silicon-rich and annealing conditions to control the size or density of silicon nanocrystals. The critical temperature required for the formation of silicon nanocrystals has been suggested by the literature as being 1000oC. We have proved this through experiments. After annealing at 900oC, the high-resolution electron photo of silicon-rich silicone oxide has a silicon content of around 30%. It is obvious that silicon nanocrystals exist.
(2) First time observation of the electroluminescence in Au/(Ge/SiO2) superlattice/pSi structure. High-resolution electron micrograph showing a four-period Ge/SiO2 supra lattice. The bright-line shows SiO2 having a thickness of 2.0nm. The Ge layer has a thickness at 2.4nm.
(3) The nanoSiO2/Si/SiO2 sandwich structure, a single-potential high-potential well structure, was grown on silicon substrates using magnetron-sputtering technology. It was the first time that visible electroluminescence from the Au/NDB/p–Si structure had been achieved. It was found that the intensity and peak positions of the electroluminescence oscillate synchromatically with changes in the thickness (W), of Nano-silicon. Further research and analysis have proven that the oscillation time is 1/2 of the de Broglie wavelength. This is explained by the electroluminescence theory proposed by our group.
(4) Er electroluminescence (with a wavelength 1.54mm) was first realized using the SiO2Si:Er film grown by magnetron-sputtering.
(5) First time, a UV-violet luminescence of 360nm at a low threshold voltage was achieved in heat-treated natural silicon oxide/pSi. It is the longest wavelength known to be produced by silicon-based ultravioletescence.
The applications prospects for Nano silicon
We have developed more than 10 types of silicon/siliconoxide nanostructures and realized the photoluminescence within the main wavelength band (including 1.54mm, 1.62mm, from the near ultraviolet to the near infrared) and the photoluminescence with the forward or reverse bias Low-threshold voltage electroluminescence. Our photoluminescence model and widely supported electroluminescence models provide the foundation for silicon-based optoelectronic Integration. It has significant scientific significance and great application potential.
