摘要

科技的快速发展导致电子设备的生产显著增加，引起了人们对电子废物的关注。瞬态电子器件，即设计为在使用后消失或溶解的器件。提供一个有希望的途径来缓解这一挑战。本文报道了基于直接磨损沉积在水溶性纸上的WS2的瞬态光电探测器的第一个演示，该探测器使用直接在衬底上绘制的石墨电极。整个装置可在≈60s内物理消失于水中，并可通过真空过滤回收电子材料。在环境条件下，器件的光响应度为≈176µa W−1。

Low‐Cost WS2 Photodetector on Water‐Soluble Paper for Transient Electronics

The rapid development of technology has led to a significant increase in the production of electronic devices, raising concerns about electronic waste (e‐waste). Transient electronics, i.e., devices designed to disappear or dissolve after use. Offer a promising route to mitigate this challenge. Here, the first demonstration of a transient photodetector is reported based on direct abrasion‐deposited WS2 on water‐soluble paper, using graphite electrodes drawn directly on the substrate. The whole device can physically disappear in water in ≈60 s, and the electronic materials can be recovered by vacuum filtration. The device shows a photoresponsivity of ≈176 µA W−1 under ambient conditions.
