Multipeaked polarons in soft potentials
(American Physical Society, 2004-08-10)
We consider a minimal coupled charge/excitation-lattice model capturing a competition between linear polaronic self-trapping and the self-focusing effects of a soft nonlinear on-site potential. The standard singlehumped ...

Pequenos polarons ligados e centros de cor em topázio
(Universidade Federal de Minas GeraisUFMG, 2010-08-04)
In the present work we studied the color beneficiation processes of colorless topaz, an abundant gemstone in Brazil. Blue topaz is the most internationally traded gemstone in the gem and market, reaching about 100 million ...
About the species formed during the electrochemical half oxidation of polyaniline: Polaron-bipolaron equilibrium
(Pergamon-Elsevier Science Ltd, 2018-04)
The UV–Vis spectra of polyaniline (Pani) films were measured in the range 200 nm–900 nm, at constant potential as well as sweeping the potential. Both free standing films and Pani films deposited on ITO substrates were ...
Mixed ion-polaron transport in lithium vanadium-molybdenum tellurite glasses
(Elsevier Science, 2006-11)
The electrical properties of mixed ion-polaron conducting vanadium tellurite glasses of the form XLi2O·(1 - X)[0.5V2O5·0.5MoO3]2TeO2 have been studied by using the impedance spectroscopy in a wide range of temperature and ...
