Abstract: Ultrathin and low-loss phase-change materials (PCMs) are highly valued for their fast and effective phase transitions and applications in reconfigurable photonic chips, metasurfaces, optical modulators, sensors, photonic memories, and neuromorphic computing. However, conventional PCMs mostly… read more here.

DOI: 10.1021/acs.nanolett.4c05880
Abstract: Dielectric metasurfaces operating at quasi-bound states in the continuum (qBICs) can achieve exceptionally high radiative quality (Q) factors by introducing small asymmetries into their unit cells. However, fabrication imperfections often impose major limitations on the… read more here.
