Abstract

The 2023 2nd International Conference on Semiconductors, Electromagnetics and Condensed Matter Physics (SECMP 2023) took place during July 21st to 23rd, 2023 in Qingdao, China (virtual form). SECMP exists as an international annual conference which tries to meet the needs for semiconductors, electromagnetics and condensed matter physics and has been established as a high-quality international conference.The Conference encouraged the exchange of information on research frontiers in different fields, connected the most advanced academic resources at home and abroad, and turned research results into industrial solutions. It also promoted the development of the field of semiconductors, electromagnetics and condensed matter physics, expanded the international scientific and academic exchange channels, enhanced scientific innovation on a global scale, and contributed to academic cooperation between China and foreign countries.The Conference was attended by more than 50 participants and hosted 7 keynote speeches, as well as various oral presentations and poster presentations. The 2nd SECMP covered various research fields where semiconductors, electromagnetics and condensed matter physics are used, such as Semiconductor Nano and Devices, Microwave Photonic Device Physics, Printed and Conformal Antennas, Solid State Quantum Information and Computing, Quantum Simulation, etc.According to all attendees, the scientific program was excellent with high level of talks and the scientific environment was fruitful, thus all attendees had a great and creative time. Professor Lai Chin Wei from University of Malaya, Malaysia reported on Titanium Dioxide Nanomaterials for advanced environmental applications. Titanium dioxide (TiO2) is one of the most attractive transition-metal oxides because of its superior physical and chemical properties, which has been widely applied in environmental clean-up (photocatalytic pollution removal) as well as antibacterial/antiviral coating applications. The performance of TiO2 in these applications highly depends on its structural, electronic, optical, and morphological as well as the surface properties (exposed facets). Great effort has been devoted to adjust these properties and apparent his research covered the synthesis of TiO2-based nanomaterials and their environmental related applications.We would like to express our acknowledgment to the authors for their time and genuine efforts, and to the reviewers for their fruitful comments during the preparation of this volume. We would also like to thank the members of the Program Committee for their effort in planning the program. Our gratitude also goes to Journal of Physics: Conference Series for its support in publishing this volume.The Committee of SECMP 2023List of Committee Member is available in this Pdf.
