Fine structure of the red photoluminescence band of porous silicon
A fine structure of the red photoluminescence band of porous silicon is reported. This observation is direct evidence that the visible radiation originates in Si quantum wires, where two-dimensional quantum confinement of carriers results in a widening of the Si band gap. To explain the fine structure, a model of electronic energy states in the Si wires is proposed.
