电子计数与一大类二维半导体

Electron counting and a large family of two-dimensional semiconductors

Mao-sheng Miao, Jorge Botana, Jingyao Liu, Wen Yan

摘要:

与传统的半导体材料相比,二维半导体材料的选择非常有限。基于适当的电子计数,我们提出了一个大家庭的2DSC,所有采用相同的结构,只由主族元素。利用先进的密度泛函计算,我们证明了这些材料的可实现性,并表明它们涵盖了大范围的晶格常数,带隙和带边态,因此是很好的候选材料异质结。这种二维材料家族可能为制造与3D半导体相同的繁荣水平的2DSC器件铺平道路。

英文摘要:

Comparing with the conventional semiconductors, the choice of the two dimensional semiconductor (2DSC) materials is very limited. Based on proper electron counting, we propose a large family of 2DSCs, all adopting the same structure and consisting of only main group elements. Using advanced density functional calculations, we demonstrate the attainability of these materials, and show that they cover a large range of lattice constants, band gaps and band edge states, therefore are good candidate materials for heterojunctions. This family of two dimensional materials may pave a way toward fabrication of 2DSC devices at the same thriving level as 3D semiconductors.
