Journal ArticleDOI
Charge transport in organic semiconductors.
Veaceslav Coropceanu,Jérôme Cornil,Demetrio A. da Silva Filho,Yoann Olivier,Robert J. Silbey,Jean-Luc Brédas +5 more
TL;DR: Electronic Coupling in Oligoacene Derivatives: Factors Influencing Charge Mobility, and the Energy-Splitting-in-Dimer Method 3.1.
Journal ArticleDOI
Introduction to Organic Thin Film Transistors and Design of n-Channel Organic Semiconductors
Christopher R. Newman,C. Daniel Frisbie,Demetrio A. da Silva Filho,Jean-Luc Brédas,and Paul C. Ewbank,Kent R. Mann +5 more
TL;DR: The development of air-stable n-channel organic semiconductors with improved performance in organic thin film transistors (OTFTs) is a major challenge for materials chemists as discussed by the authors.
Journal ArticleDOI
Organic semiconductors: A theoretical characterization of the basic parameters governing charge transport
TL;DR: It is shown that the amplitude of the transfer integrals is extremely sensitive to the molecular packing, and specific arrangements can lead to electron mobilities that are larger than hole mobilities, which is, for instance, the case of perylene.
Journal ArticleDOI
Effect of electronic polarization on charge-transport parameters in molecular organic semiconductors.
Edward F. Valeev,Veaceslav Coropceanu,Demetrio A. da Silva Filho,Seyhan Salman,Jean-Luc Brédas +4 more
TL;DR: It is shown that the neglect of electronic polarization leads to qualitatively incorrect values and trends for the transfer integrals computed with the energy splitting method, even in simple prototypes such as ethylene or pentacene dimers.
Journal ArticleDOI
Charge transport properties in discotic liquid crystals: a quantum-chemical insight into structure-property relationships.
Vincent Lemaur,Demetrio A. da Silva Filho,Veaceslav Coropceanu,Matthias Lehmann,Yves Geerts,Jorge Piris,Michael G. Debije,Anick M van de Craats,Kittusamy Senthilkumar,Laurens D. A. Siebbeles,J. M. Warman,Jean-Luc Brédas,Jérôme Cornil +12 more
TL;DR: A significant increase in the charge mobility when going from triphenylene to hexaazatrinaphthylene is predicted; this finding has been confirmed by measurements carried out with the pulse-radiolysis time-resolved microwave conductivity technique.
