Examples

  • Physicists at the University of California, San Diego have for the first time observed the spontaneous production of coherence within "excitons," the bound pairs of electrons and holes that enable semiconductors to function as novel electronic devices.

    It's Supposed to Be Republican Territory

  • This is where the quantum confinement effects become very useful, as the effects couple photogenerated electrons and holes into bound electron-hole pairs called excitons, and encourage the efficient formation of more than one exciton from a single absorbed photon.

  • An international team of researchers has developed a numerical modeling technique to study specific types of particles called excitons, which consist of a positively and a negatively charged electron and hole, respectively.

  • Physicists at UC San Diego have successfully created speedy integrated circuits with particles called "excitons" that operate at commercially cold temperatures, bringing the possibility of a new type of

  • Some time back I thought about using black holes, white holes and euclideanized gravity solutions as a model for instantons and excitons, but abandoned the effort.

  • By then my research interests had broadened, and I was using picosecond laser techniques to look at excitons as a potential system for observing metal-insulator transitions and Anderson localization.

  • We show the estimated biexciton resonance (XX*) at 1 meV below the quantum-well excitons '(X) energy, 1,484.57 meV.

  • To generate multiple excitons, the MEG process must compete with the rapid cooling of initial photogenerated high-energy excitons (called "hot excitons").

  • The excess energy of hot excitons or hot carriers can quickly lose their excess kinetic energy through electron-phonon interactions and convert it into heat, which accounts for significant loss of conversion efficiency.

  • The hot excitons are created by the absorption of energetic blue or near-ultraviolet photons.
