我们通过在 p 型 NiO 薄膜顶部精确排列 n 型 SnO2 纳米带，提出了一种高度透明的异质结光电二极管。该p-n结二极管表现出稳定的整流特性以及大大增强的紫外光响应，具有高达10(5)的超高光敏度，并且在反向偏压下响应速度加快。
We present a highly transparent heterojunction photodiode by precisely aligning n-type SnO2 nanobelts on top of a p-type NiO thin film. This p-n junction diode demonstrates stable rectifying characteristics as well as greatly enhanced ultraviolet photoresponse, which exhibits an ultrahigh photosensitivity of up to 10(5) with accelerated response speed under reverse bias.
