硼富勒烯的第一性原理研究

Boron Fullerenes: A First-Principles Study

Nevill Gonzalez Szwacki

摘要:

用第一性原理局域密度泛函方法研究了一系列异常稳定的硼笼。富勒烯的结构类似于B12二十面体,由六个交叉的双环组成。能量最稳定的富勒烯由180个硼原子组成。富勒烯家族和它的前体,硼片,之间的连接。我们表明,最稳定的硼片不一定是非常稳定的硼笼的前体。我们的发现是理解最近生产的硼纳米管结构的一个进步。

英文摘要:

A family of unusually stable boron cages was identified and examined using first-principles local density functional method. The structure of the fullerenes is similar to that of the B12 icosahedron and consists of six crossing double-rings. The energetically most stable fullerene is made up of 180 boron atoms. A connection between the fullerene family and its precursors, boron sheets, is made. We show that the most stable boron sheets are not necessarily precursors of very stable boron cages. Our finding is a step forward in the understanding of the structure of the recently produced boron nanotubes.
