Seminario INMA impulso: Nanooptics in 2D materials
El miércoles 10 de mayo tendrá lugar una nueva sesión del ciclo de conferencias INMA-Impulso, un ciclo de conferencias que trata de acercar la investigación más puntera a la sociedad.
La próxima sesión titulada: “Nanooptics in 2D materials” correrá a cargo de Pablo Alonso-González de la universidad de Oviedo and Center of Research on Nanomaterials and Nanotechnology (CINN)
Resumen de la charla:
Van der Waals (vdW) materials have recently attracted considerable attention due to their ability to support nanolight (polaritons) with unique properties, such as hyperbolic dispersion, negative phase velocity, or extreme confinement. In particular, the biaxial vdW semiconductor α-phase molybdenum trioxide (α-MoO3) has received much attention due to its ability to support in-plane hyperbolic phonon polaritons (PhPs) —infrared (IR) light coupled to lattice vibrations in polar materials— with ultra-low losses, offering an unprecedented platform for controlling the flow of energy at the nanoscale.
In this seminar, I will show experimental demonstrations of the unique behavior of PhPs in these crystals, including the visualization of anomalous cases of the fundamental optical phenomena of refraction and reflection, and the exotic phenomenon of canalization, in which PhPs propagate along a single direction with ultralow losses when two biaxial slabs are rotated at a critical angle (Twistoptics).
Los seminarios INMA-Impulso están organizados por el Instituto de Nanociencia y Materiales de Aragón, INMA, instituto mixto del CSIC y la Universidad de Zaragoza.
La conferencia tendrá lugar el miércoles 10 de mayo a las 12 horas en la Sala de Grados de la Facultad de Ciencias de la Universidad de Zaragoza.
