Hot-carrier mediated photon upconversion in metal/semiconductor heterostructure

Not Accessible

Your library or personal account may give you access

Abstract

We experimentally demonstrate a new photon upconversion technique based on hot-carriers in plasmonic systems. We show that metallic nanostructures on GaN/InGaN multiquantum well can upconvert ~2.48 eV photons to 2.82 eV photons via a linear process.
