Multiple Tunable Hyperbolic Resonances in Broadband Infrared Carbon-Nanotube Metamaterials
John Andris Roberts, Po-Hsun Ho, Shang-Jie Yu +5
Aligned, densely-packed carbon nanotube metamaterials prepared using vacuum filtration are an emerging infrared nanophotonic material. We report multiple hyperbolic plasmon resonan…
Tunable Hyperbolic Metamaterials Based on Self-Assembled Carbon Nanotubes
John Andris Roberts, Shang-Jie Yu, Po-Hsun Ho +3
We show that packed, horizontally aligned films of single-walled carbon nanotubes are hyperbolic metamaterials with ultra-subwavelength unit cells and dynamic tunability. Using Mue…
Intrinsically ultrastrong plasmon-exciton interactions in crystallized films of carbon nanotubes
Po-Hsun Ho, Damon B. Farmer, George S. Tulevski +6
In cavity quantum electrodynamics, optical emitters that are strongly coupled to cavities give rise to polaritons with characteristics of both the emitters and the cavity excitatio…
Strong and broadly tunable plasmon resonances in thick films of aligned carbon nanotubes
Kuan-Chang Chiu, Abram L. Falk, Po-Hsun Ho +5
Low-dimensional plasmonic materials can function as high quality terahertz and infrared antennas at deep subwavelength scales. Despite these antennas' strong coupling to electromag…
Environment-insensitive and gate-controllable photocurrent enabled by bandgap engineering of MoS2 junctions
Fu-Yu Shih, Yueh-Chun Wu, Yi-Siang Shih +6
Two-dimensional (2D) materials are composed of atomically thin crystals with an enormous surface-to-volume ratio, and their physical properties can be easily subjected to the chang…
Demonstration of distinct semiconducting transport characteristics of monolayer graphene functionalized via plasma activation of substrate surfaces
Po-Hsiang Wang, Fu-Yu Shih, Shao-Yu Chen +7
We report semiconducting behavior of monolayer graphene enabled through plasma activation of substrate surfaces. The graphene devices are fabricated by mechanical exfoliation onto…
