摘要:

傳統二維材料具有豐富的電學、光學特性，在電子器件領域中占據著重要位置。金屬元素摻雜二維過渡族金屬硫化物不僅可以保持原過渡族金屬硫化物所特有的優越性能，還可賦予二維材料特定的鐵磁、鐵電性能，使其在光學器件、自旋電子學器件以及信息和數據存儲等領域得到更廣泛的應用。重點介紹了金屬元素摻雜過渡族金屬硫化物的理論和制備方法，對其結構特性、電子特性以及磁學特性進行了詳細討論，并且著重論述了金屬元素摻雜在過渡族金屬硫化物中的實驗合成方法。其中，化學氣相沉積法、化學氣相傳輸法被廣泛使用，其他實驗方法如固相法、磁控濺射法也可結合運用。最后展望了金屬元素摻雜過渡族金屬硫化物研究面臨的挑戰以及未來磁性二維材料的發展方向。

Abstract:

Traditional two�瞕imensional materials show great potential application in the field of electronic devices because of its abundant electro�瞣ptical properties. Metal�瞐tom�瞕oping in transition metal dichalcogenides can not only preserve their unique optical and electronic properties, but also may give rise to new ferromagnetic and ferroelectric properties, which will open a new application field in spintronics, information storage, and transmission. In this paper, we focus on the theoretical and synthesis study of metal elements doped transition metal dichalcogenides, as well as their structure, electronic and magnetic properties. The experimental synthesis methods of metal atom�瞕oped transition metal dichalcogenides are emphatically discussed, in which chemical vapor deposition and chemical vapor transport methods are widely used, and other ways such as solid state reaction and magnetron sputtering method can also be used together with other methods. Finally, the challenges of metal�瞐tom�瞕oping in transition metal dichalcogenides and the development of magnetic two�瞕imensional materials are prospected.
