摘要:

傳統(tǒng)二維材料具有豐富的電學(xué)、光學(xué)特性，在電子器件領(lǐng)域中占據(jù)著重要位置。金屬元素?fù)诫s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(yōu)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(xué)器件、自旋電子學(xué)器件以及信息和數(shù)據(jù)存儲等領(lǐng)域得到更廣泛的應(yīng)用。重點(diǎn)介紹了金屬元素?fù)诫s過渡族金屬硫化物的理論和制備方法，對其結(jié)構(gòu)特性、電子特性以及磁學(xué)特性進(jìn)行了詳細(xì)討論，并且著重論述了金屬元素?fù)诫s在過渡族金屬硫化物中的實(shí)驗(yàn)合成方法。其中，化學(xué)氣相沉積法、化學(xué)氣相傳輸法被廣泛使用，其他實(shí)驗(yàn)方法如固相法、磁控濺射法也可結(jié)合運(yùn)用。最后展望了金屬元素?fù)诫s過渡族金屬硫化物研究面臨的挑戰(zhàn)以及未來磁性二維材料的發(fā)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.
