研究领域
原子层材料与器件
一、电化学微纳器件:以微纳加工技术和自建测量平台为研究手段,拟开展“电子器件+电化学”交叉学科的研究。
1)从半导体物理学的角度来认识和理解电化学过程中的电子行为(如“自门控”效应和“优化电子传输”方案),提取物理化学反应过程中的“物理特征”;
2)设计新型的微纳电化学器件、发展电化学过程的原位电学/电化学/材料特性多维度表征手段。
二、高效电子器件:设计原子层厚度的高性能晶体管,和基于type II异质结的光电探器件。
三、新型原子层材料的晶圆级合成。
Research Fields
Atom-thin Materials and Devices
1. Electrochemical micro-nano devices: with micro-nano processing technology and self-built measurement platform as the research means, we plan to carry out the interdisciplinary research of "electronic-devices + electrochemistry".
1.1 With a point view of semiconductor physics, we aim to understand the electronic behavior in the electrochemical process (such as the "self-gating" effect and "optimized electron-transport"), and to extract the "physical signature" in the Physico-chemical reaction process.
1.2 Design new micro/nano electrochemical devices and develop in-situ electrochemical/electrochemical/material characterization methods for electrochemical processes.
2. High-efficient electronic devices: high-performance atom-thin transistors, and Type II heterojunction-based optoelectronic detectors.
3. Wafer-scale synthesis of novel atom-thin materials.
