二维黑磷烯作为新一代半导体材料,具有可调带隙和高载流子迁移率等优点,具有广阔的应用前景.但二维黑磷烯目前还不能直接大规模制备,限制了其进一步的研究和应用.分子束外延是一种广泛使用的具有较高外延质量的单晶薄膜生长方法,在制备二维黑磷烯方面具有广阔的应用前景.本文基于密度泛函理论计算筛选了ZnO(110)、GaN(110)、BP(110)和SiC(110)四种潜在的衬底,研究了二维黑磷烯在这些衬底上的生长情况.研究表明,ZnO(110)上的黑磷单层及团簇结构是稳定的,且磷在该表面扩散特性也有助于磷团簇的成核生长.本研究为高效制备二维黑磷烯及其他二维材料提供了有益的指导.
Epitaxial Growth of Black Phosphorene Monolayer on ZnO(110)Substrate
As a new generation of semi-conductor materials,two-di-mensional black phospho-rene(BlackP)has broad ap-plication prospects because of its tunable band gap and high carrier mobility.Howev-er,BlackP cannot be directly prepared on a large scale at present,which limits its fur-ther research and applica-tion.Molecular beam epitaxy is a widely used way to grow single crystal films with higher epi-taxial quality,which is promising for preparing BlackP.Herein,four potential substrates ZnO(110),GaN(110),BP(110)and SiC(110)were screened,and the growth of BlackP on these substrates was studied based on first principles.Our study shows that the structure of black phosphorus monolayer on ZnO(110)is stable and P diffusion on this surface has desir-able properties for BlackP growth.This study provides useful guidances for the effective preparation of BlackP and the growth of other two-dimensional materials.
