While basic features of polarons were well recognized a long time ago and have been described in a number of review papers and textbooks, interest in the role of electron-phonon interactions and polaron dynamics in contemporary materials has recently gone through a vigorous revival.

A polaron is a quasiparticle consisting of an electron and an ionic polarization field. The electron density is low so the screening by electrons can be Size: KB.

Exciton polarons dressed with a cloud made of several phonons exist as a new phase in the f.c.c. lattice between the phase of self-trapped excitons dressed with much more phonons and that of free excitons essentially undressed. The exciton polaron in the new phase moves slowly resonating among localized polaron states whose phonon cloud has a Cited by: 5.

Bipolarons and polaronic excitons Although two electrons (or two holes) repel by the Coulomb interaction, two electron polarons (or two hole polarons) can in theory have a net attractive force, due to the attraction of each to the lattice distortion induced by the other.

They point out that, for the formation of a molecular polaron or self-trapped exciton, a potential barrier must be penetrated or surmounted by the configuration coordinate, leading to a delay in the self-trapping by: In this publication, details of the calculation of heat conductivity and thermal diffusivity, compressibility, sound velocity and exciton‐polaron dispersion will be shown.

The properties of excitons, coupling to phonons, producing thus polarons, but also blocking the phonons as running waves lead to an exciton condensation or exciton liquid. Surprisingly, this exciton liquid is contained in Author: Peter Wachter.

The dynamics of negative polaron and triplet exciton transport within a series of monodisperse platinum (Pt) acetylide oligomers is reported. The oligomers consist of Pt–acetylide repeats, [PtL2–C≡C–Ph–C≡C−]n (where L = PBu3 and Ph = 1,4-phenylene, n = 2, 3, 6, and 10), capped with naphthalene diimide (NDI) end groups.

The Pt–acetylide segments are electro- and photoactive, and Cited by: Part of the Physics of Solids and Liquids book series (PSLI) In crystals of insulators and semiconductors, when an incident photon is absorbed exciting an electron from the valence to the conduction band, a positive charged vacancy, called a hole, is created in the valence by: 1.

Excitons and polaritons in an optical lattice filled with ultracold atoms in the Mott insulator phase represent an idealized form of an optically excitable solid state crystal.

Modeling by a two-component Bose-Hubbard model allows us to derive the quantum phase diagram identifying the regions of Mott insulator phases. Polarons and Bipolarons: An Introduction.

October ; DOI: / in Polarons and Excitons, edited by C. Kuper and G. Whitfield (Plenum Press, New York, ), p. Singlet excitons can be dissociated into polarons —charges leading to an ultrafast reorganization of the nonrigid organic molecules on which they reside—by charge transfer.

Thus, only one of the two constituents of an exciton, electron or hole, migrate to another molecule. The absence of delayed fluorescence at such times as well as other observations lead to the conclusion that the mechanism responsible for this resonance is the nonradiative quenching of singlet excitons by the polarons, whose population decreases at the field-for- resonance.

Finally, the principal quasi-particles (phonons, polarons, excitons, plasmons, and polaritons) that are fundamental to explaining phenomena such as component aging (phonons) and optical performance in terms of yield (excitons) or communication speed (polarons) are discussed.

It explains the concept of the polaron physics in as simple a manner as possible and presents the theoretical techniques and mathematical derivations. The conformational structure and the electronic properties of various electronic excitations in cycloparaphenylenes (CPPs) are calculated using hybrid density functional theory (DFT).
