Wafer-scale monodomain films of spontaneously aligned single-walled carbon nanotubes
(Springer Nature, 2016)
The one-dimensional character of electrons, phonons and excitons in individual single-walled carbon nanotubes leads to extremely anisotropic electronic, thermal and optical properties. However, despite significant efforts ...
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 ...
Electrically tunable hot-silicon terahertz attenuator
(AIP Publishing LLC, 2014)
We have developed a continuously tunable, broadband terahertz attenuator with a transmission tuning range greater than 103. Attenuation tuning is achieved electrically, by simply changing the DC voltage applied to a heating ...
Efficient Modulation of 1.55 μm Radiation with Gated Graphene on a Silicon Microring Resonator
(American Chemical Society, 2014)
The gate-controllability of the Fermi-edge onset of interband absorption in graphene can be utilized to modulate near-infrared radiation in the telecommunication band. However, a high modulation efficiency has not been ...
Probing low-density carriers in a single atomic layer using terahertz parallel-plate waveguides
(The Optical Society, 2016)
As novel classes of two-dimensional (2D) materials and heterostructures continue to emerge at an increasing pace, methods are being sought for elucidating their electronic properties rapidly, non-destructively, and ...
