: excitónico
  • Excitonic behavior can significantly influence the optical properties of semiconductors.
  • excitonic condensate
  • excitonic effects

Examples

  • Because the excitonic binding energy is so weak—approximately three orders of magnitude weaker than for a hydrogen atom—excitons exist only at temperatures around 10 K.

  • The long-sought evidence for an excitonic condensate has now surfaced in a different and unexpected quarter: a quantum Hall bilayer.

    Academic text (2004)
  • This type of confinement enhances excitonic effects.

    Academic text (1994)
  • Experimenters have been searching ever since for excitonic condensates.

    Academic text (2004)
  • The excitonic ac Stark effect has been extensively investigated both experimentally and theoretically.

    Academic text (1994)
  • Excitonic binding also plays a major role in the theories of gap excitations of the fractional quantum Hall effect.

    Academic text (1994)
  • The evidence for excitonic condensates comes from both electron-doped and hole-doped bilayers.

    Academic text (2004)
  • As this thermalization takes place, the excitonic absorption is strongly reduced because thermalized carriers begin reaching the bottom of the bands.

    Academic text (1994)
  • Sankar Das Sarma of the University of Maryland, College Park, comments that the recent experiments have demonstrated an excitonic condensate but not necessarily a superfluid.

    Academic text (2004)
  • This effect has attracted a lot of attention because it can be viewed as a Bose condensation of populations in all the excitonic states stimulated by the "symmetry breaking" pump field.

Morphology

excitonic = exciton (transparent) = exciton + ic

Formed by the regular adjectival suffix '-ic' on the noun 'exciton', meaning 'relating to excitons'.

Etymology

The word excitonic comes from exciton, a name made from excite, meaning 'to make active', and the particle ending -on. So excitonic means 'relating to excitons', the tiny bound pair of an electron and a hole inside a material that can change how the material behaves with light.
