Superconducting topological Dirac semimetals: -Si and -NaSi
Alex Takyung Lee, Kyungwha Park, In-Ho Lee
We theoretically propose that hexagonal silicon-based crystals, -Si and -NaSi, are topological Dirac semimetals with superconducting critical temperatures of 12…
Toward Monoatomic-Layer Field Confinement Limit via Acoustic Graphene Plasmons
In-Ho Lee, Tony Low, Luis Martín-Moreno +2
Vertical plasmonic coupling in double-layer graphene leads to two hybridized plasmonic modes: optical and acoustic plasmons with symmetric and anti-symmetric charge distributions a…
Mode-matching enhancement of second-harmonic generation with plasmonic nanopatch antennas
Ahsan Noor, Anoop R. Damodaran, In-Ho Lee +3
Plasmonic enhancement of nonlinear optical processes confront severe limitations arising from the strong dispersion of metal susceptibilities and small interaction volumes that ham…
Real-space imaging of acoustic plasmons in large-area CVD graphene
Sergey G. Menabde, In-Ho Lee, Sanghyub Lee +8
An acoustic plasmonic mode in a graphene-dielectric-metal heterostructure has recently been spotlighted as a superior platform for strong light-matter interaction. It originates fr…
Ultrastrong plasmon-phonon coupling via epsilon-near-zero nanocavities
Daehan Yoo, Fernando de León-Pérez, In-Ho Lee +6
Vibrational ultrastrong coupling (USC), where the light-matter coupling strength is comparable to the vibrational frequency of molecules, presents new opportunities to probe the in…
Image polaritons in boron nitride for extreme polariton confinement with low losses
In-Ho Lee, Mingze He, Xi Zhang +8
Polaritons in two-dimensional materials provide extreme light confinement that is difficult to achieve with metal plasmonics. However, such tight confinement inevitably increases o…
Anisotropic Acoustic Plasmons in Black Phosphorus
In-Ho Lee, Luis Martin-Moreno, Daniel A. Mohr +3
Recently, it was demonstrated that a graphene/dielectric/metal configuration can support acoustic plasmons, which exhibit extreme plasmon confinement an order of magnitude higher t…
Tunable Graphene Metasurface Reflectarray for Cloaking, Illusion and Focusing
Sudipta Romen Biswas, Cristian E Gutiérrez, Andrei Nemilentsau +4
We present a graphene-based metasurface that can be actively tuned between different regimes of operation, such as anomalous beam steering and focusing, cloaking and illusion optic…
