Quantum dots can be realised in semiconductors if researchers lock an electron and an electron hole -- i.e.
The results presented here corroborate recent ultrafast experimental evidence suggesting that free polarons can form on an ultrafast time scales (sub-100 fs) and that thermally activated low frequency torsional modes are key in effective electron hole separation in PPV/PCBM heterojunctions.
The investigation of the photocatalytic activity indicated that the as-prepared Zn-doped Sn[O.sub.2]/[Zn.sub.2]Sn[O.sub.4] nanocomposites exhibit enhanced photocatalytic activities in the degradation of MB under UV light irradiation compared with that of pure [Zn.sub.2]Sn[O.sub.4], which is ascribed to the effective separation of photoinduced electron hole pairs.
The Landau damping actually is dephasing, where coherent field oscillations are transformed into incoherent electron hole pairs, but the total energy of the system is not changed.
Recombination is a process by which a conduction band electron loses energy and re-occupies the energy state of an electron hole in the valence band.
Excitons are particle-like entities consisting of an electron and an electron hole (a positive charge attributed to the absence of an electron).
Unlike silicon solar cells, though, energy absorption of the conducting polymer results in formation of an exciton, or electron hole pair, rather than free-flowing electrons and holes pushed by an internal field.
The nanorods absorb light of a particular wavelength and generate an electron plus an electron hole. The electron travels the length of the nanorod and is collected by the aluminum electrode.
The initial transfer of an electron from the chlorophyll in the reaction center leaves an "electron hole" in the chlorophyll that is soon refilled.
