Polaron crossover in molecular solids

Spin-Crossover Molecular Solids Beyond Rigid Crystal Approximation

The qualitative analysis of the spin-crossover molecular solid with distortion effect is presented. A spin-crossover solid with effect of distortion is studied in the framework of the Ising-like model with two-order parameters under statistical approach, where the effect of elastic strain on inter-ion interaction is considered. These considerations lead to examination of the relation between th...

Transport through a molecular quantum dot in the polaron crossover regime

Polaron Dynamics in Organic Molecular Stacks

Organic semiconductors have emerged as ideal candidates for the design of optoelectronic devices such as photovoltaics 1 and light-emitting 2 diodes due to present important traits which are required for the development of new green energy solutions. The potential advantages in terms of low cost, flexibility, and low environmental impact make these materials attractive for the electronics indus...

Fermi-liquid-to-polaron crossover. I. General results.

We use analytic techniques and the dynamical mean field method to study the crossover from fermi liquid to polaron behavior in models of electrons interacting with dispersionless classical phonons. Typeset using REVTEX

Exciton dispersion in molecular solids.

The investigation of the exciton dispersion (i.e. the exciton energy dependence as a function of the momentum carried by the electron-hole pair) is a powerful approach to identify the exciton character, ranging from the strongly localised Frenkel to the delocalised Wannier-Mott limiting cases. We illustrate this possibility at the example of four prototypical molecular solids (picene, pentacene...
