Broadband Detection Based on 2D Bi<sub>2</sub>Se<sub>3</sub>/ZnO Nanowire Heterojunction

Broadband Detection Based on 2D Bi<sub>2</sub>Se<sub>3</sub>/ZnO Nanowire Heterojunction

The investigation of photodetectors with broadband response and high responsivity is essential. Zinc Oxide (ZnO) nanowire has the potential of application in photodetectors, owing to the great optoelectrical property and good stability in the atmosphere. However, due to a large number of nonradiativ...
