Chip-Scale Aligned Chiral Carbon Nanotubes Exhibiting Giant Second Harmonic Generation
Rui Xu, Jacques Doumani, Viktor Labuntsov +16
Chiral carbon nanotubes (CNTs) are direct-gap semiconductors with optical properties governed by one-dimensional excitons with enormous oscillator strengths. Each species of chiral…
Unified Quantification of Quantum Defects in Small-Diameter Single-Walled Carbon Nanotubes by Raman Spectroscopy
Finn L. Sebastian, Felicitas Becker, Yohei Yomogida +5
The covalent functionalization of single-walled carbon nanotubes (SWCNTs) with luminescent quantum defects enables their application as near-infrared single-photon sources, as opti…
Controlled synthetic chirality in macroscopic assemblies of carbon nanotubes
Jacques Doumani, Minhan Lou, Oliver Dewey +9
There is an emerging recognition that successful utilization of chiral degrees of freedom can bring new scientific and technological opportunities to diverse research areas. Hence,…
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…
Band Structure Dependent Electronic Localization in Macroscopic Films of Single-Chirality Single-Wall Carbon Nanotubes
Weilu Gao, Davoud Adinehloo, Ali Mojibpour +7
Significant understanding has been achieved over the last few decades regarding chirality-dependent properties of single-wall carbon nanotubes (SWCNTs), primarily through single-tu…
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…
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…
Experimental determination of the local optical conductivity of a semiconducting carbon nanotube and its modification at individual defects
Ryosuke Senga, Thomas Pichler, Yohei Yomogida +3
Measurements of optical properties at nanometre-level are of central importance for characterization of optoelectronic device. It was, however, hardly possible for the conventional…
