Origin of the Background Absorption in Carbon Nanotubes: Phonon-Assisted Excitonic Continuum
Stefano Dal Forno, Natsumi Komatsu, Michael Wais +8
Excitonic effects in 1D semiconductors can be qualitatively different from those in higher dimensions. In particular, the Sommerfeld factor, the ratio of the above-band-edge excito…
Control of high-harmonic generation by tuning the electronic structure and carrier injection
Hiroyuki Nishidome, Kohei Nagai, Kento Uchida +4
High-harmonic generation (HHG), which is generation of multiple optical harmonic light, is an unconventional nonlinear optical phenomenon beyond perturbation regime. HHG, which was…
Groove-Assisted Global Spontaneous Alignment of Carbon Nanotubes in Vacuum Filtration
Natsumi Komatsu, Motonori Nakamura, Saunab Ghosh +7
Ever since the discovery of carbon nanotubes (CNTs), it has long been a challenging goal to create macroscopically ordered assemblies, or crystals, of CNTs that preserve the one-di…
Templated direct growth of ultra-thin double-walled carbon nanotubes
Lei Shi, Jinquan Wei, Kazuhiro Yanagi +5
Double-walled carbon nanotubes (DWCNTs) combined the advantages of multi-walled (MW-) and single-walled (SW-) CNTs can be obtained by transforming the precursors (e.g. fullerene, f…
Extraction of Linear Carbon Chains Unravels the Role of the Carbon Nanotube Host
Lei Shi, Kazuhiro Yanagi, Kecheng Cao +3
Linear carbon chains (LCCs) have been shown to grow inside double-walled carbon nanotubes (DWCNTs) but isolating them from this hosting material represents one of the most challeng…
Direct Observation of Cross-Polarized Excitons in Aligned Single-Chirality Single-Wall Carbon Nanotubes
Fumiya Katsutani, Weilu Gao, Xinwei Li +4
Optical properties of single-wall carbon nanotubes (SWCNTs) for light polarized parallel to the nanotube axis have been extensively studied, whereas their response to light polariz…
