| However, because quantum confinement gives solar-cell designers another way to fine-tune cells, they think the method is worth exploring. These new results show "strong evidence" that quantum confinement occurring in such superlattices may "allow us to turn silicon into a shining example of an optoelectronic material," Miller says in Nature. Some researchers attribute the glow to quantum confinement effects in microscopic silicon "wires" left behind after etching: Electrons confined by these wires recombine with positive charges to produce light. |
