TL;DR: In this article, the fundamental limits of plasmon damping in graphene were determined using nanometre-scale infrared imaging at cryogenic temperatures, and plasman polaritons were observed to propagate over 10'micrometres in high-mobility encapsulated graphene.

TL;DR: In this article, the propagation of plasmon polaritons in twisted bilayer graphene (TBG) was studied by infrared nano-imaging, and it was shown that the atomic reconstruction occurring at small twist angles transforms the TBG into a natural plasmor photonic crystal for propagating nano-light.

TL;DR: The fundamental limits to plasmon damping in graphene are determined using nanoscale infrared imaging at cryogenic temperatures, and pl asmon polaritons are observed to propagate over 10 micrometres in high-mobility encapsulated graphene.

TL;DR: It is discovered that the atomic reconstruction occurring at small twist angles transforms the TBG into a natural plasmon photonic crystal for propagating nano-light, pointing to a pathway for controlling nano- light by exploiting quantum properties of graphene and other atomically layered van der Waals materials, eliminating the need for arduous top-down nanofabrication.

TL;DR: In this paper, the authors demonstrate a broadly tunable two-dimensional photonic crystal for surface plasmon polaritons for on/off control of light propagation in integrated optical circuits.
