Porous silicon: Quantum sponge structures grown via a self-adjusting etching process


  • [AMSC111]


Electroluminescence in porous silicon at room temperature has recently been achieved. This is a crucial step in the realization of silicon-based optoelecctronic devices but there is still work to be done, for example in improving the stability of the electroluminscence. The materials, the effect, and the potential of the materials in the study of quantum confinement effects in silicon sspongess (see figure) are discussed.
