Quantum-Dot Leap
Abstract:
For the past half century, the limit of one electron per solar photon seemed a regrettable fact of semiconductor physics. However, in recent tests of semiconductor bits only a few nanometers in diameter - entities known as nanocrystals or quantum dots - researchers have been surprised to find that photons at solar energies commonly unleash multiple electrons.
