Photoconductivity of Colloidal Quantum Dot Films in Plasmonic Nanogaps

Photoconductivity of Colloidal Quantum Dot Films in Plasmonic Nanogaps

We investigate the photoconductivity properties of lead sulphide (PbS) quantum dot ensembles in lithographically tailored gold electrodes with smallest gaps of 15 nm. We demonstrate that quantum dots are reliable nanoscale light/current converters and correlate the measured photocurrents to the quan...
