Universality in the Photophysics of pi-Conjugated Polymers and Single-Walled Carbon Nanotubes
Sumit Mazumdar, Zhendong Wang, Hongbo Zhao
We describe both pi-conjugated polymers and semiconducting single-walled carbon nanotubes because of the remarkable similarities in their behavior under photoexcitation. The common…
Photophysics of charge-transfer excitons in thin films of π-conjugated polymers
Zhendong Wang, Sumit Mazumdar, Alok Shukla
We develop a theory of the electronic structure and photophysics of interacting chains of π- conjugated polymers to understand the differences between solutions and films. While ph…
Electron-electron interaction effects on the photophysics of metallic single-walled carbon nanotubes
Zhendong Wang, Demetra Psiachos, Roberto F. Badilla +1
Single-walled carbon nanotubes are strongly correlated systems with large Coulomb repulsion between two electrons occupying the same orbital. Within a molecular Hamiltonian a…
Essential optical states in -conjugated polymer thin films
Zhendong Wang, Sumit Mazumdar, Alok Shukla
We develop a theory of the electronic structure and photophysics of interacting chains of -conjugated polymers to understand the differences between solutions and films. While p…
pi-Electron theory of transverse optical excitons in semiconducting single-walled carbon nanotubes
Zhendong Wang, Hongbo Zhao, Sumit Mazumdar
We present a quantitative theory of optical absorption polarized transverse to the tube axes in semiconducting single-walled carbon nanotubes. Transverse optical absorption in semi…
Quantitative calculations of the excitonic energy spectra of semiconducting single-walled carbon nanotubes within a -electron model
Zhendong Wang, Hongbo Zhao, Sumit Mazumdar
Using Coulomb correlation parameters appropriate for -conjugated polymers (PCPs), and a nearest neighbor hopping integral that is arrived at by fitting the energy spectra of thr…
