Topic Graphene optoelectronics and plasmonics
Abstract
Recent advances in 2D van der Waals materials opened the door to a new plethora of exciting optical phenomena and applications. In particular, 2D materials are interesting as their optical response resides across the sought after mid-infrared spectrum, which finds applications in gas and biomolecule sensing and free space communications, near-infrared spectrum for telecommunications, and the visible spectrum. This series of seminars is divided into two parts. The first part is geared towards introducing basic concepts of the optoelectronic and plasmonic properties of 2D, such as carrier statistics, 2D electrostatics, optical conductivity, light scattering and absorption, and plasmon modes in 2D, using graphene as a prime example. In the second part, I will provide my perspective on where 2D optoelectronics and plasmonics might be most promising and unique in terms of applications. I will discuss how graphene metasurface can be constructed to focus mid-infrared light, to reflect them defying Snell’s law, and illusion optics. I will explain why graphene plasmonics is uniquely suited as a tunable platform for biomolecular and gas fingerprinting, and discuss recent theory and experiments on this front. Finally, I hope to impress upon you that the wide range of electronic properties in 2D materials opens the door to the engineering of a plethora of novel mid-infrared plasmonic effects which has to-date been inaccessible in conventional plasmonic materials like bulk noble metals. This includes slow plasmons in bilayer graphene, chiral plasmons in twisted bilayer graphene, hyperbolic plasmons in anisotropic materials, Berry plasmons in massive Dirac like materials, plasmons immune to Landau damping in finite electronic width materials, and current driven amplified plasmons in WTe2.
