Key aspect/summary of your research project项目简介 本项目旨在研发一种基于ZnO/钙钛矿/ZnO异质结双极型光电晶体管（HBPTs）的新型自供电柔性光电探测器。通过集成压电效应与热释电效应，该器件无需外部电源即可工作，因而特别适用于可穿戴健康监测、低功耗物联网环境感知以及下一代人机交互界面。研究将重点阐明压电与热释电极化之间的耦合机制，优化界面与能带结构，并展示出一种具有显著提升的响应度和探测率的柔性器件。本工作致力于开发面向日常应用的高能效、强适应性传感解决方案，促进光电设备走向可持续发展。 This project aims to develop a novel self-powered flexible photodetector based on ZnO/perovskite/ZnO heterojunction bipolar phototransistors (HBPTs). By integrating piezoelectric and pyroelectric effects, the device can operate without an external power source, making it particularly suitable for wearable health monitoring, low-power IoT environmental sensing, and next-generation human-machine interactive interfaces. The research will focus on understanding the coupling mechanism between piezoelectric and pyroelectric polarization, optimizing interface and band structures, and demonstrating a flexible device with significantly improved responsivity and detectivity. This work seeks to provide an energy-efficient and adaptable sensing solution for daily-life applications, promoting the development of sustainable and user-friendly optoelectronic systems. 有意者请将个人简历及其他有助于申请的材料发送至 zhangguohe@xjtu.edu.cn or wen.liu@xjtlu.edu.cn 注:不用跟帖，直接发邮件就行，主题请注明博士申请。 |
