Tailoring phonon-driven responses in α-MoO3 through isotopic enrichment
Thiago S. Arnaud, Ryan W. Spangler, Johnathan D. Georgaras +29
The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material is…

Ultraconfined THz Phonon Polaritons in Hafnium Dichalcogenides
R. A. Kowalski, N. S. Mueller, G. Álvarez-Pérez +18
The confinement of electromagnetic radiation to subwavelength scales relies on strong light-matter interactions. In the infrared (IR) and terahertz (THz) spectral ranges, phonon po…
