Using a dot with a smaller band gap increases the expected number of excitons because less energy is needed to push each electron over the threshold, Klimov explains. A paper published in the June 2, 2003, issue of Applied Physics Letters describes a simulation of tomographic reconstruction using scanning transmission electron micrographs of a model photonic band gap crystal. John described photonic band gap materials, which may lead to the development of improved communication devices. |
