The 7th International Conference on Optoelectronic Materials and Devices (ICOMD 2025) has successfully concluded.

On December 27, 2025, the 7th International Conference on Optoelectronic Materials and Devices (ICOMD 2025) concluded successfully in Zhuhai. The conference was hosted by Sun Yat-sen University, organized by the School of Microelectronics Science and Technology of Sun Yat-sen University. It attracted over 80 experts, scholars, and industry elites from domestic and international universities, research institutions, and enterprises, who gathered to engage in in-depth exchanges and discussions on cutting-edge technologies and innovative applications in the field of optoelectronic materials and devices.

At the beginning of the conference, following a brief yet solemn opening ceremony delivered by Associate Professor ZhengjiXu of Sun Yat-sen University, the highly anticipated plenary session commenced. Several top experts from the industry took the stage one after another, presenting a series of brilliant and insightful academic reports.

First, Professor Zhang Daohua from Shenzhen Pinghu Laboratory delivered a report titled "Research Progress on Fourth-Generation Semiconductors." Following this, Professor Zheng Wei from Sun Yat-sen University gave an outstanding lecture on "Vacuum Extreme Ultraviolet Detection Technology." Next, Professor He Tingchao from Shenzhen University presented a report titled "Construction, Optical Properties, and Application Research of Chiral Semiconductors." Professor Dong Bo from Shenzhen Technology University then delivered a report on "Tactile Sensors Enabled by Flexible Thin-Film Bulk Acoustic Wave Resonators." Finally, Professor Mohammad Syuhaimi Ab-Rahmanfrom the National University of Malaysia presented a report titled "Towards a Future of WDM-POF Network with User and Environmentally Friendly Features." 

Moreover, four scholars from Sun Yat-sen University sharing cutting-edge research findings. Associate Professor Haoran Mu introduced two-dimensional van der Waals heterojunction photodetectors featuring low dark current and high sensitivity, with some devices achieving multi-level photoelectron storage and real-time spectral recognition. Associate Professor Zhiqiang Yang focused on lithium niobate–sulfide heterogenous platform acousto-optic modulator chips, demonstrating their applications in microwave photonics and advancements in heterogeneous integrated modulators. Associate Professor Shipu Xu proposed interface engineering strategies for low-dimensional materials to enhance gas sensing, photodetection, and pressure sensing performance. Assistant Professor Zhanfeng Huang shared fabrication techniques for all-inorganic perovskite photodetectors, developing high-quality thin-film devices and demonstrating underwater wireless optical communication suitable for low-light motion recognition.

The subsequent oral presentation session featured young scholars sharing their latest research findings in their respective fields.

The conference achieved fruitful results, greatly promoting academicexchange and collaboration in the field of optoelectronic materials and devices. Furthermore, the conference served as a bridge for communication and cooperation among universities, research institutions, and enterprises, helping to advance the deep integration of industry, academia, and research, and accelerating the transformation and application of scientific achievements.

The successful convening of the 7th International Conference on Optoelectronic Materials and Devices (ICOMD 2025) has injected newvitality into the development of the optoelectronic materials and devices field and has also provided clear direction for its future growth. We look forward to seeing more innovative achievements in future research that will drive greater breakthroughs in optoelectronic materials and device technologies.
