An efficient MSM UV photodetector with an ultra-low dark current enhanced by a back to back TiO2/PbTiO3 PN heterojunction

A TiO2 MSM UV photodetector has been extensively researched and exhibits many good properties such as stability and a large ratio of light to dark current. However, it suffers from a high dark current and slow response and recovery. In this work, an MSM UV photodetector based on a TiO2/PbTiO3 hetero...
