His research interests focus on the discovery of novel multifunctional materials, rich solid materials and device physics using methods of first-principles computation and theoretical simulation, and their applications in next-generation electronic and magnetic spintronic devices. It includes the following aspects:
1: Study the novel quantum states and their applications in two-dimensional metal-organic framework and covalent organic framework materials, such as the unique physical properties brought by various non-mediocre topological states and zones. 2: Research and design quantum spin Hall and anomalous Hall materials for high-performance spintronic devices through theoretical calculation and model analysis 3: Research on Basic physical Properties and device Physics of novel multi-functional quantum Materials

It has long been committed to exploring electronic and magnetic materials with high application value through theoretical research, and studying their rich material physics and device physics. The main research achievements include: 1) The first discovery of topological materials with Lieb structure, revealing the formation and strengthening mechanism of high temperature organic ferromagnetism; 2) Explore new magnetic outer ear semi-metallic materials with topological flat bands, and propose new physical principles to achieve ultra-high anomalous Hall effect for magnetic spintronic devices; 3) A series of novel topological states are found in organic frame materials, which is expected to realize organic ferromagnetic superconductivity and quantum spin liquids and various topological quantum Hall effects; 4) Propose the working principle and regulatory mechanism of organic molecules in the next generation of electronic devices. So far, he has published more than 40 papers in international high-level SCI journals. Contains the first/corresponding author articles [Nat.Commun.],[Phys.Rev. Lett.],[Nano Lett.],[Acc.Chem. Res.], [Nanoscale], [Phys.Rev.b], etc., cited more than 1000 times. Invited as first author to publish a review of novel quantum states in organic frame materials in [AC.chem.res.] and the classic book "World Scientific Reference on spin in organic spintronics" Write the chapter 'Organic topological insulators' in the book Organics.
