Studies of hot photoluminescence in plasmonically-coupled silicon via variable energy excitation and temperature dependent spectroscopy

Carlos O. Aspetti, Chang-Hee Cho, Rahul Agarwal +1

By coupling silicon nanowires (~150 nm diameter, 20 micron length) with an Ω-shaped plasmonic nanocavity we are able to generate broadband visible luminescence, which is induced by…
