The academic seminar titled "Frontiers of Quantum States in 2D Semiconductors", organized by the IQMD at the Liaoning Academy of Materials, was successfully held on February 22-23. This seminar provided in-depth discussions on the photoelectromagnetic physical phenomena and recent advancements in 2D semiconductor materials and devices, while also exploring the future application prospects of novel quantum states within these systems.

In recent years, 2D semiconductor materials have become a research frontier in condensed matter physics and material science due to their unique electronic band structures, strong electron correlations, and excellent optoelectronic properties. With continuous advances in preparation and control technologies, 2D semiconductors have made new progress in areas such as the discovery of new material systems, mass production methods, improvements in transistor uniformity, and controllable doping routes. Additionally, a series of groundbreaking developments have been made in fundamental research directions, including novel low-dimensional quantum states and topological nontrivial physics. 2D semiconductor materials provide researchers with a physics platform full of opportunities and challenges from both applied research and fundamental research perspectives.

Against this background, the forum covered a range of physical research topics in 2D semiconductors through five discussion sessions: (1) 2D Semiconductor Spectroscopy Research, (2) Flat-band Topology and 2D Twisted Electronics, (3) New States in 2D Semiconductors, (4) New Low-Dimensional Semiconductor Materials and Device Fabrication, and (5) Models and Theories. These topics spanned various research areas such as quantum dot physics, future high-performance semiconductors, correlated states, spectroscopy, and magnetoelectric transport. Numerous experts and scholars from domestic universities and research institutions participated in academic exchanges on these topics. Through excellent invited talks and several open discussion sessions, participants had the opportunity to share, exchange, and spark new inspirations.

Jiang Xiangwei, Director of the Physics Division at the Mathematical and Physical Sciences Department of the National Natural Science Foundation of China (NSFC), was invited to attend and gave the opening speech. Peng Jie, Director of the Science Communication and Achievement Transformation Center at the NSFC, briefly introduced the positioning of the FR journal sponsored by the NSFC, the foundation's science outreach efforts, and the ongoing exploration of research transformation into applications. Over twenty experts from institutions such as Peking University, ShanghaiTech University, Nanjing University, Shanghai Jiao Tong University, Beijing Normal University, Wuhan University, Fudan University, University of Electronic Science and Technology of China, Tsinghua University, University of Chinese Academy of Sciences, Westlake University, and the Institute of Physics, Chinese Academy of Sciences delivered invited talks.

This seminar provided a platform for participants to exchange ideas and share achievements, promoting academic exchanges in the field of frontier applications of new semiconductor materials and the fundamental research of quantum states within these materials. It also laid a solid foundation for further future scientific collaborations among the attending experts and scholars. We look forward to these cutting-edge studies being translated into practical applications, driving the development of relevant scientific and technological fields.
