In his presentation, Loh Kian Ping introduced the topological electronic structure characteristics and unique electronic properties of topological insulators and Weyl semimetals. Topological insulators possess specific properties in their interior, while their surface exhibits extraordinary electronic states that significantly influence electronic conduction and material properties. Weyl semimetals feature Weyl fermions near the Fermi level of their electronic band structure, serving as tangible manifestations of topological properties and playing a pivotal role in electron transport and optical properties. In various application fields, such as electronics, optoelectronics, quantum computing, and topological quantum physics, topological insulators and Weyl semimetals hold vast potential. Due to their distinctive electronic properties, these materials offer avenues for the advancement of novel electronic devices and materials, fueling extensive research interest in academia. Professor Loh Kian Ping's presentation endeavors to delve into the topological characteristics of these two materials and investigate their potential applications in materials science and electronics. It emphasizes the pivotal role and transformative value of topological materials in condensed matter physics and materials science.
