Phase-dependent electronic structure of two-dimensional Ag layers at the graphene/SiC interface
Sawani Datta, Boyang Zheng, Arpit Jain +4
Intercalation at the graphene/SiC interface provides a controlled route to stabilize atomically thin layers with properties distinct from their bulk counterparts. In this platform,…
Ultra-Confinement of Polaritons in Single Atomic Layer Ag Photonic Quantum Dots
Xinyi Li, Tetyana Ignatova, Chengye Dong +8
Light scattering by two-dimensional (2D) van der Waals heterostructures (vdWHs) is immense, especially given their infinitesimal volume, thus enabling strong light-matter interacti…
Ultrafast photo-thermoelectric currents in graphene junctions in the mid-infrared
Nina Pettinger, Michel Panhans, Johannes Schmuck +8
Graphene is widely recognized for its ultrafast and broadband photocurrent response, but whether the broadband ultrafast characteristics are preserved at mid-infrared wavelengths w…
Superconducting Decoherence and Thermal Quenching of the Josephson Diode Effect in Low-Dimensional Josephson Systems
F. Yang, C. Y. Dong, Joshua A. Robinson +1
Motivated by recent studies on superconducting (SC) diode nonreciprocity, we uncover a generic smooth SC-phase decoherence mechanism in low-dimensional Josephson structures. Contra…
Ultrafast Band-Gap Renormalization in Bilayer Graphene
Eduard Moos, Zhi-Yuan Deng, Hauke Beyer +6
We demonstrate, by femtosecond time- and angle-resolved photoemission spectroscopy, that photoinduced interlayer charge transfer in a heterostructure consisting of Bernal-stacked b…
Point defects and their dynamic behaviors in silver monolayer intercalated between graphene and SiC
Van Dong Pham, Arpit Jain, Chengye Dong +4
Point defects give rise to sharp modifications in the structures and electronic properties of two-dimensional metals, offering an atomic-level platform for fundamental studies and…
