近年來在層狀材料過渡金屬二硫?qū)倩铮═MD）的電子結(jié)構(gòu)、理論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) 基于群論的對稱性分析提出了一個(gè)描述TMD單層的三帶TB模型，該模型能夠有效的描述該類體系的低能電子結(jié)構(gòu)，被國內(nèi)外同行廣泛認(rèn)可及使用，引用率達(dá)200次以上 [PRB 88, 085433 (2013)]。(2) 提出了一個(gè)雙層TMD在±K谷處的低能有效k.p模型，可描述雙層TMD中自旋、谷以及層三個(gè)自由度間的耦合并基于此研究了谷控的磁電耦合效應(yīng)；此外還預(yù)言了雙層TMD在±K谷具有自旋依賴的圓極化光選擇定則以及空穴輸運(yùn)的自旋霍爾效應(yīng)。該工作已被引用100次以上 [Nat Comm 4, 2053 (2013)]。(3) 為探究在實(shí)際應(yīng)用中有限體系里谷自由度是否依然有效，研究了量子點(diǎn)限制勢在單層TMD中引起的谷間耦合，兩種不同的理論方法一致表明在小至幾十納米的TMD單層量子點(diǎn)中谷間耦合依然是很小的，谷依然是有效的自由度，為TMD單層在谷電子學(xué)的器件應(yīng)用上掃除了理論上的重大顧慮。該工作已被引用20次以上 [New J Phys 16, 105011 (2014)]。(4) 從能帶特征、對稱性、激子效應(yīng)、自旋軌道耦合效應(yīng)、能谷依賴的特性以及與Berry相位相關(guān)的物理屬性等多個(gè)方面對單層及雙層TMD的電子結(jié)構(gòu)進(jìn)行了綜述與評論；此外，還總結(jié)和比較了當(dāng)時(shí)各種近似下描述二維TMD的理論模型并對它們各自的特點(diǎn)及適用范圍進(jìn)行了深入的分析與評論。該工作對深入理解TMD層狀材料的電子結(jié)構(gòu)及相關(guān)物性有著重要的理論參考價(jià)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層狀材料方面還有一系列合作研究的工作，其中最具影響力的當(dāng)數(shù)2012年關(guān)于TMD單層的研究，該研究中我們開創(chuàng)性的研究了TMD單層中谷與自旋耦合的豐富物理內(nèi)容，包括谷依賴的Berry曲率和軌道磁矩、谷依賴的圓極化光選擇定則、谷霍爾效應(yīng)以及自旋霍爾效應(yīng)等，奠定了TMD材料在谷電子學(xué)中的重要地位，該工作已被引用1300以上 [PRL 108, 196802 (2012)]。
