Switched photocurrent direction in Au/TiO 2 bilayer thin films

Chen, Hongjun; Liu, G; Wang, Lianzhou


Switched photocurrent direction in photoelectrodes is a very interesting phenomenon and has demonstrated their potentials in important applications including photodiodes, phototransistors, light-driven sensors and biosensors. However, the design and mechanism understanding of such photoelectrodes remain challenging to date. Here we report a new phenomenon of sequence-driven the photocurrent direction on a simple bilayer structure of 5 nm thick Au and 10 nm TiO2 under visible-light irradiation....[Show more]
