Résumé

While the integration of nanocrystals as an active medium for optoelectronic devices progresses, light management strategies become required. Over recent years, several photonic structures (plasmons, cavities, mirrors, etc.) have been coupled to nanocrystal films to shape the absorption spectrum, tune the directionality, and so on. Here, we explore a photonic equivalent of the acoustic Helmholtz resonator and propose a design that can easily be fabricated. This geometry combines a strong electromagnetic field magnification and a narrow channel width compatible with efficient charge conduction in spite of hopping conduction. At 80 K, the device reaches a responsivity above 1 A•W-1 and detectivity above 10 11 Jones (3 µm cutoff) while offering a significantly faster time-response than vertical geometry diodes.
