Abstract

Lead sulfide is an important photosensitive material, and its photoelectric properties have received widespread attention. We completed the preparation of PbS nanowires and single PbS nanowire devices, then we conducted electrical performance tests on the PbS nanowire devices. We found that a single lead sulfide nanowire device exhibits memristive properties that depend on the applied voltage and the power density of light. From this we studied the electrical transport properties of single lead sulfide nanodevices.
