Dimerization structures on the metallic and semiconducting fullerene tubules
Possible dimerization patterns and electronic structures in fullerene tubules as the one-dimensional π-conjugated systems are studied with the extended Su-Schrieffer-Heeger model. We assume various lattice geometries, including chiral and achiral tubules. The model is solved for the half-filling case of πelectrons. (1) When the undimerized systems do not have a gap, the Kekulé structures prone ...

متن کاملDimerization and Energy-level Structures in Fullerene Tubules Investigated with an Electron-phonon Model
Possible dimerization patterns and electronic structures in fullerene tubules as the π-conjugated systems are studied with the extended Su-Schrieffer-Heeger model. We assume various lattice geometries, including helical and nonhelical tubules, and tubules with end caps. The model is solved for the half-filling case of π-electrons. (1) When the undimerized systems do not have a gap, the Kekulé s...
متن کاملPolychiral semiconducting carbon nanotube-fullerene solar cells.
Single-walled carbon nanotubes (SWCNTs) have highly desirable attributes for solution-processable thin-film photovoltaics (TFPVs), such as broadband absorption, high carrier mobility, and environmental stability. However, previous TFPVs incorporating photoactive SWCNTs have utilized architectures that have limited current, voltage, and ultimately power conversion efficiency (PCE). Here, we repo...
متن کاملNovel metastable metallic and semiconducting germaniums
Group-IVa elements silicon and germanium are known for their semiconducting properties at room temperature, which are technologically critical. Metallicity and superconductivity are found at higher pressures only, Ge β-tin (tI4) being the first high-pressure metallic phase in the phase diagram. However, recent experiments suggest that metallicity in germanium is compatible with room conditions,...
