Refraction of Hyperbolic Polaritons using Phase Change Materials
Oct. 26, 2018—We are delighted to say that our work on controlling hyperbolic polaritons in hBN using the phase change material VO2 has been published in Nature Comms! Also – Check out Tom and Josh’s News and Views published in nature this week!
Our work probing hyperbolic polaritons using infrared attenuated total reflectance was just published in MRS Communications!
Oct. 2, 2018—We’re very excited to have published our work using the attenuated total reflectance technique to probe the hyperbolic phonon polaritons in hexagonal boron nitride. This technique is a great new tool in exploring a host of 2D materials! Check it out here.
Our work chosen as an one of the Top Advances in Engineering!

Gordon Research Seminar and Conference on Plasmonics and Nanophotonics
Jul. 22, 2018—Tom, Joseph, and Ryan attended and presented posters at the Gordon Research Seminar and Conference on Plasmonics and Nanophotonics in Newry, ME! Tom discussed his recent work on reconfigurable hyperbolic mid-infrared metasurfaces, Joseph presented on the identification of dark hyperbolic modes in hexagonal boron nitride nanostructures with the photothermal induced resonance technique (which was work...
Congrats to Jack on an Excellent Summer SSMV research term!
Jul. 11, 2018—Jack Allen, a rising senior at MLK High School in Nashville, has been working with our group as part of the School for Science and Math at Vanderbilt (SSMV). His work focused on measuring angle dependent, infrared reflection spectra from bulk crystals of transition metal dichalcogenides and extracting the corresponding IR dielectric functions. It has...
Check out our new publication in the design of graphene plasmon resonant cavities!
Jul. 11, 2018—Congrats to my coauthors, Xiaofei and Xiaofeng for this new work on the “Theoretical Analysis of Graphene Plasmon Cavities” that was published in Applied Materials Today! Thanks to Vincenzo Giannini and Stefan Maier for including me in this work!
New Publication on Strong Coupling in Phonon-Polariton systems
Jun. 19, 2018—Congratulations to Nikolai for his publication ‘Strong Coupling of Epsilon-Near-Zero Phonon Polaritons in Polar Dielectric Heterostructures’ in Nano letters. We show that the epsilon near zero mode in a thin film of aluminium nitride strongly couples to a phonon polariton in Silicon Carbide. This work features simulations and analysis by Tom.
Combined group outing!
May. 16, 2018—Had a wonderful day on the Harpeth river with the Valentine group. Really enjoyed the lazy morning off and great to get the groups together outside of the lab and conference rooms! Some pictures are below: Just starting out! The Valentine and Caldwell groups ready to go! From left to right: Claire Marvinney (Haglund group,...
