Project A1 seeks to probe the fundamental microscopic mechanisms responsible for the properties of phase change materials, both by careful quantum-theoretical simulations and by experimentation. Recent work in our groups reveals that crystalline phase-change materials utilize a novel bonding mechanism located between metallic, covalent, and ionic bonding. To explore which materials fall into the realm of metavalent bonding, we will determine the borders of metavalent bonding with respect to ionic, metallic and covalent bonding with a combined experimental and theoretical investigation.

项目A1旨在通过仔细的量子理论模拟和实验来探索负责相变材料特性的基本微观机制。我们小组最近的工作表明，结晶相变材料利用了位于金属键、共价键和离子键之间的新型键合机制。为了探索哪些材料属于间价键合的范畴，我们将结合实验和理论研究，确定间价键合相对于离子，金属和共价键合的边界。
