亚10 nm单晶有机-无机范德华异质结让光电晶体管在激子扩散极限下突破增益-速度权衡
Breaking the Gain–Speed Trade‐Off in Phototransistors With Sub‐10 nm Single‐Crystalline Organic–Inorganic van der Waals Heterojunctions at the Exciton‐Diffusion Limit
AI 导读
研究者把双层 C6-DPA 分子晶体集成到单层 MoS2 沟道上，制成亚10 nm 单晶有机-无机范德华异质结光电晶体管，在各自优化条件下实现 1.07×10^5 A W−1 的响应度、771.2/809.8 µs 的上升/衰减时间和 2.19×10^15 Jones 的比探测率。
推荐理由
通过把有机-无机异质结减薄到激子扩散极限，作者把光电晶体管增益从陷阱介导改为界面电荷转移门控，给出了一条绕开增益-速度权衡的器件路线。
