Intramolecular electron transfer: Simple theory of purely electronic effects
Mark A. Ratner,Mary Jo Ondrechen +1 more
TL;DR: Within a simple model hamiltonian of extended Huckel, Hubbard or CNDO type, this paper derived, using perturbation theory, an expression for the effective transfer rate of an electron or hole from one region within the molecule to another.

Electrical Conductivity in the Hubbard Model Including Electron‐Phonon Interaction
TL;DR: Using the Hubbard model including weak electron-phonon coupling the electrical conductivity σ is calculated for U ≫ t (U intra-atomic Coulomb energy, U nearest-neighbour hopping integral) and low frequencies as mentioned in this paper.

Switching the charge state of individual surface atoms at Si(111)-√3 × √3:B surfaces.
TL;DR: The structural and electronic properties of the two charge states as well as their energetics are uncovered by employing scanning tunneling microscopy measurements and density functional theory calculations, which reveals that one of theTwo is a two-electron bound state or surface bipolaron.

Frequency dependence of the real part of the electrical conductivity for TTF-TCNQ
H. Hinkelmann,H.G. Reik +1 more
TL;DR: In this article, the infrared data of Heeger and Garito can be qualitatively explained using expressions from polaron theory with parameters from the literature, without the inclusion of intrasite Coulomb repulsion.
