Mid-infrared optical properties of pyrolytic boron nitride in the 390 to 1050 C temperature range using spectral emissivity measurements
Iñigo González de Arrieta, Telmo Echániz, Raquel Fuente +4
This paper shows a systematic experimental and theoretical study on the temperature dependence of the infrared optical properties of pyrolytic boron nitride (pBN), from 390 to 1050…
Spectrally Sharp Near-Field Thermal Emission: Revealing Some Disagreements between a Casimir-Polder Sensor and Predictions from Far-Field Emittance
J. C. de Aquino Carvalho, I. Maurin, P. Chaves de Souza Segundo +3
Near-field thermal emission largely exceed blackbody radiation, owing to spectrally sharp emission in surface polaritons. We turn Casimir-Polder interaction between Cs(7P1/2) and a…
Radiative Thermal Rectification between SiC and SiO2
Karl Joulain, Younes Ezzahri, Jérémie Drevillon +2
By means of fluctuationnal electrodynamics, we calculate radiative heat flux between two pla-nar materials respectively made of SiC and SiO2. More specifically, we focus on a first…
Phonons and Hybrid Modes in the High and Low Temperature Far Infrared Dynamics of Hexagonal TmMnO3
Néstor E. Massa, Leire del Campo, Domingos De Sousa Meneses +3
We report on TmMnO3 far infrared emissivity and reflectivity spectra from 1910 K to 4 K. At the highest temperature the number of infrared bands is lower than that predicted for ce…
High Temperature Far Infrared Dynamics of Orthorhombic NdMnO3: Emissivity and Reflectivity
Néstor E. Massa, Leire del Campo, Domingos De Sousa Meneses +3
We report on near normal far- and mid-infrared emission and reflectivity of NdMnO3 perovskite from room temperature to sample decomposition above 1800 K. At 300 K the number infrar…
Paramagnetic Collective Electronic Mode and Low Temperature Hybrid Modes in the Far Infrared Dynamics of Orthorhombic NdMnO3
Néstor E. Massa. Leire del Campo, Domingos De Sousa Meneses, Patrick Echegut +2
We report on far- and mid-infrared reflectivity of NdMnO3 from 4 K to 300K. Two main features are distinguished in the infrared spectra: active phonons in agreement with the expect…
Collective Phase-like Mode and the Role of Lattice Distortions at TN~TC in RMn2O5 (R= Pr, Sm, Gd, Tb, Bi)
Néstor E. Massa, Ali F. García-Flores, Domingos De Sousa Meneses +5
We report on electronic collective excitations in RMn2O5 (R= Pr, Sm, Gd, Tb) showing condensation starting at and below TN\simTC\sim40-50 K. Its origin is understood as partial del…
Infrared emissivity spectroscopy of a soda-lime silicate glass up to the melt
Cristiane N. Santos, Domingos de S. Meneses, Valérie Montouillout +1
The short-range structure of an iron doped soda-lime glass was investigated by infrared emissivity spectroscopy from room temperature up to the melt. Quantitative information on th…
High Temperature Emissivity, Reflectivity, and X-ray absorption of BiFeO3
Néstor E. Massa, Leire del Campo, Domingos De Sousa Meneses +5
We report on the lattice evolution of BiFeO3 as function of temperature using far infrared emissivity, reflectivity, and X-ray absorption local structure. A power law fit to the lo…
