摘要
由低维（0D、1D 和 2D）材料构建的范德华（vdW）异质结构正在成为下一代柔性光电探测中最具吸引力的系统之一。目前，手工堆叠的 vdW 型光电探测器与大面积阵列制造不兼容，而且在自供电模式下表现平平。本文首次提出了晶圆级垂直一维 GaN 纳米棒阵列（NRAs）/二维 MoS2/PEDOT:PSS 自供电柔性光电探测器阵列。得益于 GaN NRAs 的强光吸收和 II 型异质结中高效的光生载流子分离，该集成器件在弱紫外光照射下无需外部偏压，便可实现 1.47 A W-1 的高响应率和 1.2 × 1011 Jones 的高探测率，以及 54/71 µs 的快速响应速度。值得注意的是，该器件的应变可调光电探测性能已得到证实。令人印象深刻的是，该器件在-0.78%应变和零偏压条件下的光响应显著增强，响应率为2.47 A W-1，探测率为2.6 × 1011 Jones，响应时间为40/45 µs，优于最先进的自供电柔性光电探测器。这项工作为制备自供电柔性光电探测的可调 vdWs 异质结构提供了一条宝贵的途径，它在柔性传感器中表现出色。
Wafer-Scale Vertical 1D GaN Nanorods/2D MoS2/PEDOT:PSS for Piezophototronic Effect-Enhanced Self-Powered Flexible Photodetectors
Highlights
Vertical 1D GaN nanorod arrays/2D MoS2/PEDOT:PSS heterostructures in wafer scale have been fabricated for flexible photodetection firstly.
Self-powered flexible photodetector at compressive strain reveals a significantly enhanced photoresponse with a responsivity of 2.47 A W−1 and response times of 40/45 µs, which are superior to the state-of-the-art flexible devices.
This work not only provides a valuable strategy for the design and construction of tunable van der Waals heterostructures, but also opens a new opportunity for flexible sensors.
期刊介绍：
Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand.
Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields.
Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
