One-dimensional van der Waals Heterostructures: Growth Mechanism and Handedness Correlation Revealed by Non-destructive TEM
Yongjia Zheng, Akihito Kumamoto, Kaoru Hisama +15
In this work, we perform a follow-up and comprehensive study on the structural details and formation mechanism of chemical vapor deposition (CVD) synthesized one-dimensional (1D) v…
Nanotube-based one-dimensional heterostructures coupled by van der Waals forces
Sofie Cambré, Ming Liu, Dmitry Levshov +3
One-dimensional (1D) van der Waals heterostructures based on carbon nanotube templates are raising a lot of excitement due to the possibility of creating new optical and electronic…
Waveguide coupled cavity-enhanced light emission from individual carbon nanotubes
D. Yamashita, H. Machiya, K. Otsuka +2
We demonstrate an individual single-walled carbon nanotube light emitter integrated onto a microcavity and a waveguide operating in the telecom wavelength regime. Light emission fr…
Hexagonal boron nitride as an ideal substrate for carbon nanotube photonics
N. Fang, K. Otsuka, A. Ishii +4
Hexagonal boron nitride is widely used as a substrate for two-dimensional materials in both electronic and photonic devices. Here, we demonstrate that two-dimensional hexagonal bor…
Super-Resolution Fluorescence Imaging of Carbon Nanotubes Using a Nonlinear Excitonic Process
K. Otsuka, A. Ishii, Y. K. Kato
Highly efficient exciton-exciton annihilation process unique to one-dimensional systems is utilized for super-resolution imaging of air-suspended carbon nanotubes. Through the comp…
Organic molecular tuning of many-body interaction energies in air-suspended carbon nanotubes
S. Tanaka, K. Otsuka, K. Kimura +4
We investigate adsorption effects of copper phthalocyanine molecules on excitons and trions in air-suspended carbon nanotubes. Using photoluminescence excitation spectroscopy, we o…
