Semiconductor nanoclusters For a semiconductor crystal, electronic excitation consists of a loosely bounded electron-hole pair, usually delocalized over a length (the Bohr radius) much longer than the lattice constant. As the size of the semiconductor cluster approaches this intrinsic delocalization length...
