TLDR
In this article, an effect of interchain electron hopping t⊥ on the structure of conventional 1-d large polaron is investigated, and it is shown that the ground state of the system undergoes a sharp transition from uniformly distributed over the chains (symmetric) polaron at γ > γ(N)c to the localized essentially 1-chain one atAbout:

Two-Dimensional Electronic Excitations in Self-Assembled Conjugated Polymer Nanocrystals
TL;DR: The relatively weak absorption bands of the delocalized polaron in the visible and near-infrared spectral ranges may help to achieve laser action in nanocrystalline polymer devices using current injection.

Polymer electronic materials: a review of charge transport
Manu Jaiswal,Reghu Menon +1 more
TL;DR: An overview of the charge transport phenomenon in semiconducting polymer materials can be found in this paper, where the dependence of carrier mobility on temperature and electric field needs to be understood in the framework of competing models based on carrier hopping, trapping/detrapping and tunneling.

Electron localization and the transition from adiabatic to nonadiabatic charge transport in organic conductors
TL;DR: It is shown that for ideal systems without disorder and thermal fluctuations in the electronic coupling between the constituent elements that the electron transport can be described as an adiabatic polaron drift process, which results in nonadiabatic hopping transport.

Polarons and their stability in poly(phenylenevinylene)
TL;DR: In this paper, a tight-binding Hamiltonian along the lines of the SSH Hamiltonian for polyacetylene was used to calculate the geometry of polaron and the distance of the polaron level from the closest band edge as a function of chain length.

Studies of polaron motion: Part I. The molecular-crystal model
TL;DR: In this paper, a model for polaron motion is described, in simplified form, incorporating the principal physical features of the problem, and the conditions under which the size of the polaron becomes comparable to a lattice spacing (small) are discussed.

Solitary excitations in deoxyribonuclei acid (DNA) double helices
TL;DR: In this article, the H-bonding energy between complementary base pairs has a more reasonable form and four modes of sine-Gordon solitons which predict the existence of the open states in DNA double helices are found by using the statistical-mechanical formalism.
