Imaging and simulation of surface plasmon polaritons on layered 2D MXenes MXenes exhibit visible-range surface plasmon polaritons, detectable with photoemission electron microscopy.

Think MXenes are cool and have been wondering about their plasmonic properties? Check out this new paper from the King Lab that was just published in Science Advances @science.org . Thanks to #openaccess you can read all about it here: www.science.org/doi/10.1126/... #chemsky

Electronic structure orientation as a map of in-plane antiferroelectricity in β′-In2Se3 A nanoscale, wide-field, imaging method reveals the structure of in-plane antiferroelectric domains.

Old post from the *other* social media. Incredibly excited that this work on our new method for antiferroelectric domain imaging using polarization-dependent PEEM is finally out in Science Advances!

Surface Plasmons in Two-Dimensional MXenes MXenes, a class of layered two-dimensional transition metal carbides and nitrides, exhibit excellent optoelectronic properties and show promise for fields ranging from photonics and communications to energy storage and catalysis. Some members of the MXene family are metallic and exhibit large in-plane conductivity, making them possibly suited for 2D plasmonics. The highly variable chemical structure of MXenes offers a broad chemical space to tune material properties for plasmonic applications, including plasmon-enhanced catalysis, surface-enhanced Raman spectroscopy (SERS), and electromagnetic shielding. However, this synthetic complexity has also presented several roadblocks in the process of moving MXene plasmonics into applications. For example, in the prototypical MXene Ti3C2Tx, there remains disagreement over the bulk plasmon energy and the assignment of a prominent resonance around 1.7 eV. We discuss fundamental models and theories of plasmon physics and apply these models to MXenes in order to clarify some of these problems. We outline the potential for hyperbolic plasmons in MXenes and propose new avenues for MXene photonics research.

New paper alert!!! A perspective article about the challenges of describing surface plasmons in MXenes.
