近年来在层状材料过渡金属二硫属化物（TMD）的电子结构、理论模型及其物性方面取得了一系列的研究成果。具有代表性的研究成果包括：(1) 基于群论的对称性分析提出了一个描述TMD单层的三带TB模型，该模型能够有效的描述该类体系的低能电子结构，被国内外同行广泛认可及使用，引用率达200次以上 [PRB 88, 085433 (2013)]。(2) 提出了一个双层TMD在±K谷处的低能有效k.p模型，可描述双层TMD中自旋、谷以及层三个自由度间的耦合并基于此研究了谷控的磁电耦合效应；此外还预言了双层TMD在±K谷具有自旋依赖的圆极化光选择定则以及空穴输运的自旋霍尔效应。该工作已被引用100次以上 [Nat Comm 4, 2053 (2013)]。(3) 为探究在实际应用中有限体系里谷自由度是否依然有效，研究了量子点限制势在单层TMD中引起的谷间耦合，两种不同的理论方法一致表明在小至几十纳米的TMD单层量子点中谷间耦合依然是很小的，谷依然是有效的自由度，为TMD单层在谷电子学的器件应用上扫除了理论上的重大顾虑。该工作已被引用20次以上 [New J Phys 16, 105011 (2014)]。(4) 从能带特征、对称性、激子效应、自旋轨道耦合效应、能谷依赖的特性以及与Berry相位相关的物理属性等多个方面对单层及双层TMD的电子结构进行了综述与评论；此外， 还总结和比较了当时各种近似下描述二维TMD的理论模型并对它们各自的特点及适用范围进行了深入的分析与评论。 该工作对深入理解TMD层状材料的电子结构及相关物性有着重要的理论参考价值，已被引用100次以上 [Chem Soc Rev 44, 2643 (2015)]。除上述研究成果以外，在TMD层状材料方面还有一系列合作研究的工作，其中最具影响力的当数2012年关于TMD单层的研究，该研究中我们开创性的研究了TMD单层中谷与自旋耦合的丰富物理内容，包括谷依赖的Berry曲率和轨道磁矩、谷依赖的圆极化光选择定则、谷霍尔效应以及自旋霍尔效应等，奠定了TMD材料在谷电子学中的重要地位，该工作已被引用1300以上 [PRL 108, 196802 (2012)]。
