Destabilization of Surfactant-Dispersed Carbon Nanotubes by Anions
The colloidal stability of surfactant-dispersed single-wall carbon nanotubes (SWCNTs) is determined by microscopic physicochemical processes, such as association, partitioning, and adsorption propensities. These processes ...
Giant Terahertz-Wave Absorption by Monolayer Graphene in a Total Internal Reflection Geometry
(American Chemical Society, 2017)
We experimentally demonstrated significant enhancement of terahertz-wave absorption in monolayer graphene by simply sandwiching monolayer graphene between two dielectric media in a total internal reflection geometry. In ...
Modulation-Doped Multiple Quantum Wells of Aligned Single-Wall Carbon Nanotubes
Heterojunctions, quantum wells, and superlattices with precise doping profiles are behind today's electronic and photonic devices based on III–V compound semiconductors such as GaAs. Currently, there is considerable interest ...
Charged iodide in chains behind the highly efficient iodine doping in carbon nanotubes
(American Physical Society, 2017)
The origin of highly efficient iodine doping of carbon nanotubes is not well understood. Relying on first-principles calculations, we found that iodine molecules (I2) in contact with a carbon nanotube interact to form ...
