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…

Understanding Disorder in Monolayer Graphene Devices with Gate-Defined Superlattices
Vinay Kammarchedu, Derrick Butler, Asmaul Smitha Rashid +2
Engineering superlattices (SLs) - which are spatially periodic potential landscapes for electrons - is an emerging approach for the realization of exotic properties, including supe…
