Uncovering the properties of homo-epitaxial GaN devices through cross-sectional infrared nanoscopy
Hossein Zandipour, Felix Kaps, Robin Buschbeck +19
Validating material performance in electrical devices is crucial to product development. For Gallium Nitride (GaN) devices, evaluating material factors such as defects, dopant conc…
Multi-resonant non-dispersive infrared gas sensing: breaking the selectivity and sensitivity tradeoff
Emma R. Bartelsen, J. Ryan Nolen, Christopher R. Gubbin +8
In applications such as atmospheric monitoring of greenhouse gases and pollutants, the detection and identification of trace concentrations of harmful gases is commonly achieved us…
Spectral tuning of hyperbolic shear polaritons in monoclinic gallium oxide via isotopic substitution
Giulia Carini, Mohit Pradhan, Elena Gelzinyte +26
Hyperbolic phonon polaritons - hybridized modes arising from the ultrastrong coupling of infrared light to strongly anisotropic lattice vibrations in uniaxial or biaxial polar crys…
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…
Unidirectional Ray Polaritons in Twisted Asymmetric Stacks
J. Álvarez-Cuervo, M. Obst, S. Dixit +25
The vast repository of van der Waals (vdW) materials supporting polaritons offers numerous possibilities to tailor electromagnetic waves at the nanoscale. The development of twisto…
Ultrafast evanescent heat transfer across solid interfaces via hyperbolic phonon polaritons in hexagonal boron nitride
William Hutchins, John A. Tomko, Dan M. Hirt +10
The efficiency of phonon-mediated heat transport is limited by the intrinsic atomistic properties of materials, seemingly providing an upper limit to heat transfer in materials and…
