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…
Interface quality in GaSb/AlSb short period superlattices
Md Nazmul Alam, Joseph R. Matson, Patrick Sohr +2
Heterostructures including the members of the 6.1Å semiconductor family (AlSb, GaSb, and InAs) are used in infrared optoelectronic devices as well as a variety of other application…
Nanoscale Phonon Spectroscopy Reveals Emergent Interface Vibrational Structure of Superlattices
Eric R. Hoglund, De-Liang Bao, Andrew O'Hara +16
As the length-scales of materials decrease, heterogeneities associated with interfaces approach the importance of the surrounding materials. Emergent electronic and magnetic interf…
Infrared permittivity of the biaxial van der Waals semiconductor -MoO from near- and far-field correlative studies
Gonzalo Álvarez-Pérez, Thomas G. Folland, Ion Errea +13
The biaxial van der Waals semiconductor -phase molybdenum trioxide (-MoO) has recently received significant attention due to its ability to support highly anisotropic pho…
Probing hyperbolic polaritons using infrared attenuated total reflectance micro-spectroscopy
Thomas G. Folland, Tobias W. W. Maß, Joseph R. Matson +7
Hyperbolic polariton modes are highly appealing for a broad range of applications in nanophotonics, including surfaced enhanced sensing, sub-diffractional imaging and reconfigurabl…
Controlling the Infrared Dielectric Function through Atomic-Scale Heterostructures
Daniel C. Ratchford, Christopher J. Winta, Ioannis Chatzakis +20
Surface phonon polaritons (SPhPs) - the surface-bound electromagnetic modes of a polar material resulting from the coupling of light with optic phonons - offer immense technologica…
Reconfigurable Mid-Infrared Hyperbolic Metasurfaces using Phase-Change Materials
Thomas G. Folland, Alireza Fali, Samuel T. White +7
Metasurfaces offer the potential to control light propagation at the nanoscale for applications in both free-space and surface-confined geometries. Existing metasurfaces frequently…
Nanoscale mapping and spectroscopy of non-radiative hyperbolic modes in hexagonal boron nitride nanostructures
Lisa V. Brown, Marcelo Davanco, Zhiyuan Sun +13
The inherent crystal anisotropy of hexagonal boron nitride (hBN) sustains naturally hyperbolic phonon polaritons, i.e. polaritons that can propagate with very large wavevectors wit…
