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…
Simplified formulas for the generation of terahertz waves from semiconductor surfaces excited with a femtosecond laser
Masayoshi Tonouchi
We derive simple formulas to explain terahertz (THz) emission from semiconductor surfaces excited by a femtosecond (fs) laser. Femtosecond optical pulses with energies larger than…
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…
Visualization of photogenerated metallic inhomogeneity in the insulating phase of PrCaMnO thin film using spatiotemporal terahertz radiation imaging
N. Kida, M. Tonouchi
Using a spatiotemporal terahertz radiation imaging technique, we visualize photogenerated metallic inhomogeneity in the charge-ordered insulating phase of PrCaMnO$_…
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…
