摘要

In article number 1908176, Joshua D. Caldwell, Alexey Y. Nikitin, Pablo Alonso‐González, and co‐workers extract the IR permittivity of the biaxial crystal α‐MoO3 by correlative far‐ and near‐field measurements, using FTIR reflectance spectroscopy and s‐SNOM polariton interferometry, thus providing both an accurate permittivity model and a novel approach to extracting dielectric functions of nanomaterials. Moreover, through density functional theory, insights into the vibrational states dictating such permittivity are revealed.
