Hyperbolic phonon-polariton electroluminescence in graphene-hBN van der Waals heterostructures
Qiushi Guo, Iliya Esin, Cheng Li +7
Phonon-polaritons are electromagnetic waves resulting from the coherent coupling of photons with optical phonons in polar dielectrics. Due to their exceptional ability to confine e…
Moiré Band Topology in Twisted Bilayer Graphene
Chao Ma, Qiyue Wang, Scott Mills +9
Recently twisted bilayer graphene (t-BLG) emerges as a new strongly correlated physical platform near a magic twist angle, which hosts many exciting phenomena such as the Mott-like…
Plasmonics in Atomically-Thin Crystalline Silver Films
Zakaria M. Abd El-Fattah, Vahagn Mkhitaryan, Jens Brede +9
Light-matter interaction at the atomic scale rules fundamental phenomena such as photoemission and lasing, while enabling basic everyday technologies, including photovoltaics and o…
Efficient Electrical Detection of Mid-Infrared Graphene Plasmons at Room Temperature
Qiushi Guo, Renwen Yu, Cheng Li +4
Optical excitation and subsequent decay of graphene plasmons can produce a significant increase in charge-carrier temperature. An efficient method to convert this temperature eleva…
Coupling-Enhanced Broadband Mid-Infrared Light Absorption in Graphene Plasmonic Nanostructures
Bingchen Deng, Qiushi Guo, Cheng Li +6
Plasmons in graphene nanostructures show great promise for mid-infrared applications ranging from a few to tens of microns. However, mid-infrared plasmonic resonances in graphene n…
Efficient Electrical Control of Thin-Film Black Phosphorus Bandgap
Bingchen Deng, Vy Tran, Hao Jiang +10
Recently rediscovered black phosphorus is a layered semiconductor with promising electronic and photonic properties. Dynamic control of its bandgap can enable novel device applicat…
