Yanfei Wu,Annabel R. Chew,Geoffrey Rojas,Gjergji Sini,Gjergji Sini,Greg Haugstad,Alex Belianinov,Sergei V. Kalinin,Hong Li,Chad Risko,Jean-Luc Brédas,Alberto Salleo,C. Daniel Frisbie +12 more
TL;DR: The results provide the first concrete link between mechanical strain and WF of an organic semiconductor and have important implications for understanding the connection between structural and electronic disorder in soft organic electronic materials.
Journal ArticleDOI
Sequential Doping Reveals the Importance of Amorphous Chain Rigidity in Charge Transport of Semi-Crystalline Polymers
TL;DR: A combination of infrared spectroscopy and theoretical simulations shows that the dopants selectively placed in the amorphous regions in the film via sequential doping result in highly localized polarons, increasing film connectivity and hence improving the overall conductivity of the film compared with the conventional doping processes.
Journal ArticleDOI
Spectral Signatures and Spatial Coherence of Bound and Unbound Polarons in P3HT Films: Theory Versus Experiment
Raja Ghosh,Annabel R. Chew,Jonathan W. Onorato,Viktoria Pakhnyuk,Christine K. Luscombe,Alberto Salleo,Frank C. Spano +6 more
TL;DR: In this article, the origin of the mid-infrared spectral features for hole absorption in doped poly(3-hexylthiophene) (P3HT) films is investigated theoretically and experimentally using a Holstein-style Hamil...
Journal ArticleDOI
Bandgap Restructuring of the Layered Semiconductor Gallium Telluride in Air
Jose J. Fonseca,Jose J. Fonseca,Sefaattin Tongay,Mehmet Topsakal,Annabel R. Chew,Alan J. Lin,Alan J. Lin,Changhyun Ko,A. V. Luce,A. V. Luce,Alberto Salleo,Junqiao Wu,Junqiao Wu,Oscar D. Dubon,Oscar D. Dubon +14 more
TL;DR: A giant bandgap reduction in layered GaTe is demonstrated and localized partial recovery of the pristine gap is achieved by thermal annealing, demonstrating that reversible band engineering in layered semiconductors is accessible through their surfaces.
