θ-Tunable Photoluminescence from Interlayer Excitons in Twisted Bilayer Graphene
Hiral Patel, Lujie Huang, Cheol-Joo Kim +2
Using resonant 2-photon excitation of interlayer electrons in twisted bilayer graphene (tBLG), we resolve photoluminescence (PL) that tunes spectrally with stacking angle, θ. This…
Strongly bound excitons dominate electronic relaxation in resonantly excited twisted bilayer graphene
Hiral Patel, Lola Brown, Yufeng Liang +3
When two sheets of graphene stack in a twisted bilayer graphene (tBLG) configuration, the resulting constrained overlap between interplanar 2p orbitals produce angle-tunable electr…
New Mechanism for Strongly Bound Excitons in Gapless Two-Dimensional Structures
Yufeng Liang, Ryan Soklaski, Shouting Huang +4
Common wisdom asserts that bound excitons cannot form in high-dimensional (d>1) metallic structures because of their overwhelming screening and unavoidable resonance with nearby co…
Photocurrent measurements of supercollision cooling in graphene
Matt W. Graham, Su-Fei Shi, Daniel C. Ralph +2
The cooling of hot electrons in graphene is the critical process underlying the operation of exciting new graphene-based optoelectronic and plasmonic devices, but the nature of thi…
Ultrafast Spectroscopy of Mid-Infrared Internal Exciton Transitions of Separated Single-Walled Carbon Nanotubes
Jigang Wang, Matt W. Graham, Yingzhong Ma +2
We report a femtosecond mid-infrared study of the broadband low-energy response of individually separated (6,5) and (7,5) single-walled carbon nanotubes. Strong photoinduced absorp…
