A photoconductive semiconductor switch based on an individual ZnS nanobelt

A photoconductive semiconductor switch (PCSS) based on an individual ZnS nanobelt (NB) was investigated. Under ultraviolet light (280 nm), the current–voltage curve shows that this PCSS is of high photosensitivity (∼104), and the response time spectrum shows that this PCSS has a fast response (typical rise time 0.07 s and decay time 0.12 s) and a high-voltage response (6.7 V). Oxygen chemisorption is responsible for the improved photoconductive properties. This PCSS is a promising candidate for future integration.
