By combining these two special characteristics, the light emission rate limitation of the silicon from indirect band gap transition mechanism can be overcome and the equally spaced array structure can act as an optical antenna to enlarge the light emission intensity. Through the improvement in the light emission performance, there is a great potential for the silicon as an opto-electronic component, moreover, because of its compatibility and stability, in principle the silicon nanostructures can be readily integrated with microelectronic circuits.Through the experiment, we have found that the Raman enhancement of factor up to 4.2 can be achieved by our currently built structures. At the moment, a more detailed analysis work for this research is still carrying on and more experimental works are needed to be done to verify that a well fabricated tunable silicon nanostructure produced by EBLS techniques can be a much better and more versatile alternative for porous silicon materials. | | ISBN: | 0-9767985-2-2 |
