Abstract:Plasmonic semiconductors offer significant advantages for the development of photodetectors with a tunable wide spectral response. Herein, we developed a plasmonic semiconductor photodetector based on the W 18 O 49 nanowire array (NWA) to achieve a tunable broadband photodetector by adjusting the plasmonic absorption intensity of the W 18 O 49 NWA. The plasmonic absorption intensity could be mediated through adjusting the free electron density of the W 18 O 49 NWA by applying the external voltage on the W 18 O… Show more
