二维异质结光电探测器

重要科研成果

1）超灵敏双异质结光电晶体管

由于二维材料较弱的光吸收特性，提高光增益是发展二维材料光电探测器的关键问题之一，然而已有的器件往往仅使用一个光栅，获得的光增益有限。通过使用MoS₂作为沟道材料、正交相氧化钼（α-MoO_3-x）为电极材料,构筑了具有α-MoO_3-x/MoS₂/α-MoO_3-x结构的光电晶体管，通过双异质结光栅间的正反馈效应，实现了二维材料光电探测器中最高的探测度 (Feng,S. et al. Nature Communications,2021,12(4094):1-8)。该晶体管在源和漏端具有双异质结，在光照条件下，电子-空穴对在源端耗尽区生成，随后在内建电场驱动下分离，载流子的浓度变化导致了源端电子势垒的降低，实现了电子注入和光增益；注入的电子又可降低漏端电子势垒，增大光电流；而这又进一步增强源极内建电场，从而实现了双异质结间的正反馈效应。该工作提出了一种具有普适性意义的提高光电探测器增益的新方法，为未来构建超灵敏光电探测器开辟了新思路，并入选了Nature Communications期刊器件类亮点论文。

2）具有新信号行为的光控二极管

已报道的光电探测器如光电二极管、光电晶体管等在光照下仅能从整流态或全关态转变为全开态，而无法从全关态转变为整流态，这严重限制了光电系统的性能和功能。例如，光电探测器阵列必须为每个像素单元配备一个选通器件，极大增加了系统的面积和功耗。通过构筑具有n-MoS₂/n-MoS₂沟道和h-BN光栅结构的光控二极管，实现了可由全关态向整流态转换的新信号行为，并实现了首个无需选通器件的光电存储阵列(Feng,S. et al,National Science Review,2022,9(nwac088):1-8)。该工作实现了具有全关态-整流态转换功能的新型光电探测器，为高集成度、低功耗和智能化的光电系统提供了一种基本器件。
