摘要
A black silicon based metal-semiconductor-metal photodetector includes a silicon substrate and a black silicon layer formed on the silicon substrate. An interdigitated electrode pattern structure is formed on the black silicon layer, which can be a planar or U-shaped structure. A thin potential barrier layer is deposited at the interdigitated electrode pattern structure. An Al or transparent conductive ITO thin film is deposited on the thin potential barrier layer. A passivation layer is provided on the black silicon layer. In the black silicon based metal-semiconductor-metal photodetector, the black silicon layer, as a light-sensitive area, can respond to ultraviolet, visible and near infrared light.
