DOI: 10.1021/acs.nanolett.5c02952
Abstract: We demonstrate angle-resolved cathodoluminescence (CL) interferometry from electron-beam-excited plasmonic and dielectric nanostructures placed above a Au-coated substrate. We use 20–30 keV electrons to coherently excite plasmon-mediated radiation, which interferes with its mirror image, providing a… read more here.

DOI: 10.1364/oe.521689
Abstract: AlGaN-based ultraviolet-C (UV-C) light-emitting diodes (LEDs) face challenges related to their extremely low external quantum efficiency, which is predominantly attributed to the remarkably inadequate transverse magnetic (TM) light extraction efficiency (LEE). In this study, we… read more here.
