Anisotropic Thermoreflectance Thermometry: A contactless frequency-domain approach to study anisotropic thermal transport

L. A. Perez, K. Xu, M. R. Wagner +6

We developed a novel contactless frequency-domain approach to study thermal transport, which is particularly convenient when thermally anisotropic materials are considered. The met…

Observation of second sound in a rapidly varying temperature field in Ge

Albert Beardo, Miquel López-Suárez, Luis Alberto Pérez +9

Second sound is known as the thermal transport regime where heat is carried by temperature waves. Its experimental observation was previously restricted to a small number of materi…

Dynamic disorder, phonon lifetimes, and the assignment of modes to the vibrational spectra of methylammonium lead halide perovskites

Aurélien M. A. Leguy, Alejandro R. Goñi, Jarvist M. Frost +11

We present Raman and terahertz absorbance spectra of methylammonium lead halide single crystals (MAPbX3, X = I, Br, Cl) at temperatures between 80 and 370 K. These results show goo…

Optical studies of gap, hopping energies and the Anderson-Hubbard parameter in the zigzag-chain compound SrCuO2

Z. V. Popovic, V. A. Ivanov, M. J. Konstantinovic +8

We have investigated the electronic structure of the zigzag ladder (chain) compound SrCuO2 combining polarized optical absorption, reflection, photoreflectance and pseudo-dielectri…
