Coexistence of multiple regimes for near-field thermal radiation between two layers supporting surface phonon polaritons in the infrared
Francoeur, M.; Mengüç, Mustafa Pınar; Vaillon, R. (American Physical Society, 2011)We demonstrate the coexistence of different near-field thermal radiation regimes between two layers supporting surface phonon polaritons (SPhPs) in the infrared. These regimes existwhen the distance of separation between ... -
Control of near-field radiative heat transfer via surface phonon-polariton coupling in thin films
Francoeur, M.; Mengüç, Mustafa Pınar; Vaillon, R. (Springer Business+Media, 2011-06)The possibility of controlling near-field radiative heat transfer with the use of silicon carbide thin films supporting surface phonon–polaritons in the infrared spectrum is explored. For this purpose, the local density ... -
Coupling of near-field thermal radiative heating and phonon Monte Carlo simulation: Assessment of temperature gradient in n-doped silicon thin film
Wong, B. T.; Francoeur, M.; Bong, V. N.-S.; Mengüç, Mustafa Pınar (Elsevier, 2014-08)Near-field thermal radiative exchange between two objects is typically more effective than the far-field thermal radiative exchange as the heat flux can increase up to several orders higher in magnitudes due to tunneling ... -
Credible intervals for nanoparticle characteristics
Charnigo, R.; Francoeur, M.; Kenkel, P.; Mengüç, Mustafa Pınar; Hall, B.; Srinivasan, C. (Elsevier, 2012-01)Solving the inverse problem of nanoparticle characterization has the potential to advance science and benefit society. While considerable progress has been made within a framework based on the scattering of surface ... -
Estimating quantitative features of nanoparticles using multiple derivatives of scattering profiles
Charnigo, R.; Francoeur, M.; Kenkel, P.; Mengüç, Mustafa Pınar; Hall, B.; Srinivasan, C. (Elsevier, 2011-05)Characterization of nanoparticles on surfaces is a challenging in verse problem whose solution has many practical applications. This article proposes a method, suitable for in situ characterization systems, for estimating ... -
Local density of electromagnetic states within a nanometric gap formed between two thin films supporting surface phonon polaritons
Francoeur, M.; Mengüç, Mustafa Pınar; Vaillon, R. (AIP Publishing, 2010)We present a detailed physical analysis of the near-field thermal radiation spectrum emitted by a silicon carbide (SiC) film when another nonemitting SiC layer is brought in close proximity. This is accomplished via the ... -
A Monte Carlo simulation for phonon transport within silicon structures at nanoscales with heat generation
Wong, B. T.; Francoeur, M.; Mengüç, Mustafa Pınar (Elsevier, 2011-04)Nanoscale phonon transport within silicon structures subjected to internal heat generation was explored. A Monte Carlo simulation was used. The simulation procedures differed from the current existing methods in which ... -
Solution of near-field thermal radiation in one-dimensional layered media using dyadic Green's functions and the scattering matrix method
Francoeur, M.; Mengüç, Mustafa Pınar; Vaillon, R. (Elsevier, 2009-12)A general algorithm is introduced for the analysis of near-field radiative heat transfer in one-dimensional multi-layered structures. The method is based on the solution of dyadic Green's functions, where the amplitude of ... -
Spectral tuning of near-field radiative heat flux between two thin silicon carbide films
Francoeur, M.; Mengüç, Mustafa Pınar; Vaillon, R. (Institute of Physics, 2010)Spectral distributions of radiative heat flux between two thin silicon carbide films separated by sub-wavelength distances in vacuum are analysed. An analytical expression for the near-field flux between two layers of ... -
Thermal impacts on the performance of nanoscale-gap thermophotovoltaic power generators
Francoeur, M.; Vaillon, R.; Mengüç, Mustafa Pınar (IEEE, 2011-06)The thermal impacts on the performance of nanoscale-gap thermophotovoltaic (nano-TPV) power generators are investigated using a coupled near-field thermal radiation, charge, and heat transport formulation. A nano-TPV device ...
