请勿采用软件简单翻译！！！ 采用扶手型与锯齿型碳纳米管C（5,5），C(9,0)模型来研究C@BNNT 体系, 且内管与外管采用同一类型管，且为相同重复单元，以保证相同管长匹配。扶手型与锯齿型C@BNNT分别采用8个与4个基本重复单元，其管长分别为1.968nm,1.704nm。内外管的两头均用氢原子饱和, 模型构建如图1. 本研究中, 不同直径的BN(n,n)纳米管(n=7~15)与C(5,5)管形成扶手型C@BNNT 体系, 不同直径的BN(m,0)纳米管(n=14~22)与C(9,0)管形成锯齿型C@BNNT体系，对C@BNNT及其内外管分别进行结构优化。通过结构优化, 确定其稳定的几何构型, 寻求最适合C(5,5)和C(9,0)管的BN纳米管。具有代表性的几种Structure of optimized C(5,5)@BN(n, n) and C(9,0)@BN(m, 0)如图2所示。结构优化及电子属性计算使用基于密度泛函理论(DFT)的DMol3 程序【34，35】, 交换相关势的处理采用广义梯度近似下的PW91【36】函数, 芯电子用有效核势(ECP)进行处理, 轨道占据参数Smearing取0.0005 a.u.. 结合Universal Forcefield理论【37，38】对其优化结构能量进行了计算。 整个计算主要通过Materials Studio软件模拟实现。 |
