Enhancement of far-field thermal emission via polaritonic cavity modes
Maelie Coral, Jose Ordonez-Miranda, Georges Hamaoui +5
Controlling thermal emission is crucial for applications involving thermophotovoltaics, thermal sensing, imaging, and camouflage. While prior studies focused on the emission of the…
Enhanced Near-Field Thermal Radiation Driven by Multiple Corner and Edge Modes in Subwavelength Square Nanowires
Jose Ordonez-Miranda, Minggang Luo, Michele Diego +4
We demonstrate that the near-field thermal radiation between subwavelength SiC nanowires with square cross sections is dominated by multiple corner and edge resonances rather than…
Intrinsic Temporal Coherence Governs Heat Transport of Zone-Folded Phonons
Xiaoyu Huang, Yuxiang Ni, Zhongwei Zhang +4
While spatial phonon coherence manifested through band folding is believed to be a key factor governing the anomalous thermal conductivity of periodic structures, we investigate ph…
Phonon dispersion of nanoscale honeycomb phononic crystal: gigahertz and terahertz spectroscopy comparison
Michele Diego, Roman Anufriev, Ryoto Yanagisawa +1
Phonons-quantized vibrational modes in crystalline structures-govern phenomena ranging from thermal and mechanical transport to quantum mechanics. In recent years, a new class of a…
Piezoelectrically driven diamond phononic nanocavity by phonon-matching scheme for quantum applications
Michele Diego, Byunggi Kim, Matteo Pirro +2
Efficiently exciting and controlling phonons in diamond nanoresonators represents a fundamental challenge for quantum applications. Here, we theoretically demonstrate the possibili…
Multiscale phonon blocking in Si phononic crystal nanostructures
M. Nomura, Y. Kage, J. Nakagawa +4
In-plane thermal conduction and phonon transport in both single-crystalline and polycrystalline Si two-dimensional phononic crystal (PnC) nanostructures were investigated at room t…
