Transition from Diffusive to Superdiffusive Transport in Carbon Nanotube Networks via Nematic Order Control
Michael Wais, Filchito Renee G. Bagsican, Natsumi Komatsu +8
The one-dimensional confinement of quasiparticles in individual carbon nanotubes (CNTs) leads to extremely anisotropic electronic and optical properties. In a macroscopic ensemble…
Terahertz Excitonics in Carbon Nanotubes: Exciton Autoionization and Multiplication
Filchito Renee G. Bagsican, Michael Wais, Natsumi Komatsu +10
Excitons play major roles in optical processes in modern semiconductors, such as single-wall carbon nanotubes (SWCNTs), transition metal dichalcogenides, and 2D perovskite quantum…
Collective Antenna Effects in the Terahertz and Infrared Response of Highly Aligned Carbon Nanotube Arrays
L. Ren, Q. Zhang, C. L. Pint +8
We study macroscopically-aligned single-wall carbon nanotube arrays with uniform lengths via polarization-dependent terahertz and infrared transmission spectroscopy. Polarization a…
Terahertz Nonlinear Superconducting Metamaterials
Caihong Zhang, Biaobing Jin, Jiaguang Han +7
We investigate the nonlinear effect of a planar superconducting metamaterial made from niobium nitride (NbN) at terahertz frequencies. As the variation of the incident intense tera…
Terahertz Dynamics of Quantum-Confined Electrons in Carbon Nanomaterials
L. Ren, Q. Zhang, S. Nanot +3
Low-dimensional carbon nanostructures, such as single-wall carbon nanotubes (SWCNTs) and graphene, offer new opportunities for terahertz science and technology. Being zero-gap syst…
Cooper Pair Breakup in YBCO under Strong Terahertz Fields
Andreas Glossner, Caihong Zhang, Shinya Kikuta +4
We show that strong electric fields of ~ 30 kV cm^(-1) at terahertz frequencies can significantly weaken the superconducting characteristics of cuprate superconductors. High-power…
Terahertz and Infrared Spectroscopy of Gated Large-Area Graphene
Lei Ren, Qi Zhang, Jun Yao +9
We have fabricated a centimeter-size single-layer graphene device, with a gate electrode, which can modulate the transmission of terahertz and infrared waves. Using time-domain ter…
Carbon Nanotube Terahertz Polarizer
L. Ren, C. L. Pint, L. G. Booshehri +8
We describe a film of highly-aligned single-walled carbon nanotubes that acts as an excellent terahertz linear polarizer. There is virtually no attenuation (strong absorption) when…
