Abstract

Understanding the charge-formation and current-extraction dynamics of a zero-dimensional/two-dimensional (0D/2D) hybrid system remains challenging. Here, by incorporating 0D carbon quantum dots with 2D F–C functionalized graphene, we designed UV photodetectors that exhibit an outstanding photoresponsivity of 4.66 × 10⁶ A W⁻¹ and noise-involved detectivity of 2.7 × 10¹⁷ jones, demonstrating frequency-dependent noise suppression.

石墨烯通道上原子薄F-C功能化介导的0D/2D柔性光电探测器的噪声抑制

了解零维/二维（0D/2D）混合体系的电荷形成和电流提取动力学仍然具有挑战性。通过将0D碳量子点与二维F-C功能化石墨烯结合，我们设计了紫外光电探测器，其光响应率为4.66 × 106 A W−1，噪声相关探测率为2.7 × 1017 jones，显示出频率相关的噪声抑制。
