Evidence for high-efficiency exciton dissociation at polymer/single-walled carbon nanotube interfaces in planar nano-heterojunction photovoltaics
Moon-Ho Ham,Geraldine L.C. Paulus,Chang Young Lee,Changsik Song,Kourosh Kalantar-zadeh,Kourosh Kalantar-zadeh,Wonjoon Choi,Jae-Hee Han,Michael S. Strano +8 more
TL;DR: It is shown that the polymer/nanotube interface itself is responsible for exciton dissociation, and a planar nano-heterojunction comprising well-isolated millimeter-long single-walled carbon nanotubes underneath a poly(3-hexylthiophene) (P3HT) layer is promising for further understanding the potential role of polymer/ nanotube interfaces for photovoltaic applications.
Journal ArticleDOI
Exciton antennas and concentrators from core–shell and corrugated carbon nanotube filaments of homogeneous composition
Jae-Hee Han,Geraldine L.C. Paulus,Ryuichiro Maruyama,Daniel A. Heller,Woo Jae Kim,Paul W. Barone,Chang Young Lee,Jong Hyun Choi,Moon-Ho Ham,Changsik Song,Cristiano Fantini,Michael S. Strano +11 more
TL;DR: This work dielectrophoretically assemble single-walled carbon nanotubes of homogeneous composition into aligned filaments that can exchange excitation energy, concentrating it to the centre of core-shell structures with radial gradients in the optical bandgap.
Journal ArticleDOI
Disorder imposed limits of mono- and bilayer graphene electronic modification using covalent chemistry.
Chih-Jen Shih,Qing Hua Wang,Zhong Jin,Geraldine L.C. Paulus,Daniel Blankschtein,Pablo Jarillo-Herrero,Michael S. Strano +6 more
TL;DR: An electrochemical approach involving phenyl-diazonium salts is used to systematically probe electronic modification in MLG and BLG with increasing functionalization for the first time, obtaining the highest conversion values to date.
Journal ArticleDOI
Excess thermopower and the theory of thermopower waves.
Joel T. Abrahamson,Bernat Sempere,Bernat Sempere,Michael Walsh,Jared M. Forman,Fatih Şen,Fatih Şen,Selda Sen,Selda Sen,Sayalee G. Mahajan,Geraldine L.C. Paulus,Qing Hua Wang,Wonjoon Choi,Michael S. Strano +13 more
TL;DR: This work presents a quantitative theory that describes the electrical dynamics of thermopOWER waves, showing that they produce an excess thermopower additive to the Seebeck prediction and underscores the potential to exceed conventional figures of merit for thermoelectricity.
Journal ArticleDOI
Understanding surfactant/graphene interactions using a graphene field effect transistor: relating molecular structure to hysteresis and carrier mobility.
Chih-Jen Shih,Geraldine L.C. Paulus,Qing Hua Wang,Zhong Jin,Daniel Blankschtein,Michael S. Strano +5 more
TL;DR: This work is the first to demonstrate the control of hysteresis, allowing it to eliminate it for sensor and device applications or to enhance it to potentially enable nonvolatile memory applications.
