1. Exciton condensates have been seen in a double quantum well systems.2. Statistically three triplet excitons will be formed for each singlet exciton . 3. An exciton can form when a photon is absorbed by a semiconductor. 4. One of the materials acts as the photon absorber and exciton donor. 5. The other material facilitates exciton dissociation at the junction. 6. Consequently, the exciton has slightly less energy than the unbound electron and hole. 7. The electron and the hole can bind to each other to form an exciton . 8. The THz field generated a coherent quantum superposition of an absorbing and a nonabsorbing exciton . 9. In simpler terms, this means a local deformation of the crystal lattice around the exciton . 10. Metal nanoparticles may be applied to the exterior of CNTs to increase the exciton separation efficiency.
