Abstract

In this paper we show that self-organization of colloidal PbSe and CdSe semiconductor nanocrystals with a size ratio of 0.57 leads to binary structures with a AB2 or a cuboctahedral AB13 lattice. The type of superlattice formed can be regulated by the relative concentration of both nanocrystals in the suspension.

摘要

在本文中，我们表明尺寸比为0.57的胶体PbSe和CdSe半导体纳米晶体的自组装会形成具有AB2或立方八面体AB13晶格的二元结构。所形成的超晶格类型可通过悬浮液中两种纳米晶体的相对浓度来调节。
