h-ErMnO3 absorbance, reflectivity and, emissivity in the THz to mid-infrared from 2 K to 1700 K: carrier screening, Fröhlich resonance, small polarons, and bipolarons
Néstor E. Massa, Leire del Campo, Karsten Holldack +4
We report the temperature dependent THz to mid-infrared response of hexagonal-ErMnO3 using absorption, reflectivity, and emissivity techniques from 2 K to 1700 K. At low temperatur…

Far- and Mid-infrared Emission and Reflectivity of Orthorhombic and Cubic ErMnO3: polarons and bipolarons
Néstor E. Massa, Leire del Campo, Karsten Holldack +4
We report on the high-temperature evolution of far- and mid- infrared reflectivity and emissivity spectra of ambient orthorhombic ErMnO3 from 12 K to sample decomposition above 180…

Elucidating the Methylammonium (MA) Conformation in MAPbBr3 Perovskite with Application in Solar Cells
Carlos A. López, María Victoria Martínez-Huerta, María Consuelo Alvarez-Galván +6
Hybrid organic-inorganic perovskites, MAPbX3 (X= halogen), containing methylammonium (MA: CH3-NH3+) in the large voids conformed by the PbX6 octahedral network, are the active abso…
