Epitaxial Growth of Oxide Thin Films and Device Integration |
In the post-Moore era, as the transistor density of integrated circuits approaches its physical limits, the performance degradation of traditional semiconductor materials under size scaling and other bottleneck issues have become major challenges in the development of the integrated circuit industry. Focusing on the next generation of process technology nodes, developing functional electronic devices based on novel semiconductor materials to compensate for the performance limitations of traditional semiconductor materials in the silicon-based technology route will be one of the important future technological directions in the integrated circuit field. Heteroepitaxial growth refers to the continuation of material B growth on substrate A. Due to the stress constraints imposed by the substrate, the crystal structure of the epitaxial film is deformed due to lattice mismatch, which induces new properties. These new properties provide the possibility for designing novel semiconductor electronic devices. Our team focuses on the epitaxial growth and performance regulation of oxide films. By controlling strain and oxygen vacancies in the films, we aim to achieve excellent electrical, magnetic, and optical properties, and based on these properties, design high-performance neuromorphic memristors, ferroelectric memories, intelligent sensors, and other functional electronic devices.

Flexible Sensing Technology and Integration |
Intelligent sensing devices, as emerging sensing technologies, have significant applications in fields such as the Internet of Things (IoT), health monitoring, and industrial automation. By integrating various sensing functions, they can detect environmental changes and physiological data in real-time, providing accurate feedback and intelligent decision support. These devices are widely used in wearable devices, smart homes, environmental monitoring, and smart healthcare. Our team focuses on the development of flexible sensors with new structures and high performance (such as piezoelectric, piezoresistive, and piezocapacitive sensors) based on flexible thin-film transfer and micro/nano-structural design. We are committed to advancing the application of intelligent sensing in areas such as smart healthcare, intelligent industry, water monitoring, smart agriculture, and emergency rescue.
