Science and applications of wafer-scale crystalline carbon nanotube films prepared through controlled vacuum filtration

Weilu Gao, Junichiro Kono

Carbon nanotubes (CNTs) make an ideal one-dimensional (1D) material platform for the exploration of exotic physical phenomena under extremely strong quantum confinement. The 1D cha…

In Pursuit of 2D Materials for Maximum Optical Response

Sunny Gupta, Sharmila N. Shirodkar, Alex Kutana +1

Despite being only a few atoms thick, single-layer two-dimensional (2D) materials display strong electron-photon interactions that could be utilized in efficient light modulators o…

Direct Observation of Cross-Polarized Excitons in Aligned Single-Chirality Single-Wall Carbon Nanotubes

Fumiya Katsutani, Weilu Gao, Xinwei Li +4

Optical properties of single-wall carbon nanotubes (SWCNTs) for light polarized parallel to the nanotube axis have been extensively studied, whereas their response to light polariz…

Microwave Photocurrent from the Helical Edge state of InAs/GaInSb Bilayers

Jie Zhang, Tingxin Li, Rui-Rui Du +1

We measure microwave photocurrent in devices made from InAs/GaInSb bilayers where both insulating bulk state and conducting edge state were observed in the inverted-band regime, co…

Photovoltages and hot electrons in plasmonic nanogaps

Douglas Natelson, Charlotte I. Evans, Pavlo Zolotavin

In metal nanostructures under illumination, multiple different processes can drive current flow, and in an open- circuit configuration some of these processes lead to the productio…
