根据描述电子 声子相互作用的Fr hlich哈密顿量 ,推导出了扶手椅形碳纳米管 (ABT(n) )的Peierls相变温度的一般表达式 ,并利用该式计算了ABT(8)和ABT(10 )的Peierls相变温度 ,结果表明ABT(n)的Peierls相变温度将随管径的增大而减小 ,并且ABT(n)在远离室温下都不会发生Peierls相变 ,仍然保持其金属性 .
According to Fr hlich Hamiltonian describing the interaction of electronic phonons, a general expression for the Peierls transition temperature of armchair carbon nanotubes (ABT (n)) is deduced and the ABT (8) and The Peierls transition temperature of ABT (10) shows that the Peierls transformation temperature of ABT (n) decreases with the increase of tube diameter, and the ABT (n) does not undergo Peierls transformation far away from room temperature. Maintain its metallic nature.
