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…
Ruddlesden-Popper chalcogenides push the limit of mechanical stiffness and glass-like thermal conductivity in single crystals
Md Shafkat Bin Hoque, Eric R. Hoglund, Boyang Zhao +20
Insulating materials featuring ultralow thermal conductivity for diverse applications also require robust mechanical properties. Conventional thinking, however, which correlates st…
Ablation threshold and temperature dependent thermal conductivity of high entropy carbide thin films
Milena Milich, Kathleen Quiambao-Tomko, John Tomko +2
High entropy carbides (HECs) are a promising new class of ultra-high temperature ceramics that could provide novel material solutions for leading edges of hypersonic vehicles, whic…
Orientation Controlled Anisotropy in Single Crystals of Quasi-1D BaTiS3
Boyang Zhao, Md Shafkat Bin Hoque, Gwan Yeong Jung +17
Low-dimensional materials with chain-like (one-dimensional) or layered (twodimensional) structures are of significant interest due to their anisotropic electrical, optical, thermal…
Plasma-induced surface cooling
John A. Tomko, Michael J. Johnson, David R. Boris +3
Here we show that, despite a massive incident flux of energetic species, plasmas can induce transient cooling of a material surface. Using time-resolved optical thermometry in-situ…
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…
Long-lived modulation of plasmonic absorption by ballistic thermal injection
John A. Tomko, Evan L. Runnerstrom, Yi-Siang Wang +9
Energy and charge transfer across metal-semiconductor interfaces are the fundamental driving forces for a broad range of applications, such as computing, energy harvesting, and pho…
