Micro/Nano Electronic Information Functional Materials and Devices

Our group is focusing on the research of micro/nano electronic information functional materials and devices, our research direction and content cover:

1. The preparation of temperature, humidity and gas sensors: including the surface texture, optoelectronic property study and passive wireless device fabrication of silicon based, SnO2 based and piezoelectric sensors. The research achievement could be applied in food and file storage, smart home, industry safety and so on;

2. The preparation and characterization of nano-materials and devices: using scanning probe technology to analyze the surface potential and doping effects of as-prepared silicon nanocrystal structures and sulfide thin films to build the model of electron transport. The research achievement could be applied in silicon based light source, floating-gate memory, thin film solar cells and so on;

3. The simulation of ferroelectric and piezoelectric materials: including the pyroelectricity property of ferroelectric bulk materials and their tunnel junction, and size dependent property of piezoelectric materials. The research achievement could be applied in high-K technology, memory, sensors and so on.

In recent years, our group has published over 80 papers in international and domestic core journals, applied over 10 patents and held several projects including the National Natural Science Foundation of China, the open project of State Key Laboratory and the Natural Science Foundation of Jiangsu Province.
