作为机电双连续体的碳纳米结构

Carbon Nanostructures as an Electromechanical Bicontinuum

Cristiano Nisoli, Paul E. Lammert, Eric Mockensturm, Vincent H. Crespi

摘要:

双场模型为石墨烯和碳纳米管中的弹性、晶格动力学和机电耦合提供了一个统一的框架,描述了光学声子、非平凡的声学分支、应变引起的能隙开放、能隙引起的声子软化、掺杂引起的变形,甚至六方石墨烯布里渊区,从而解释和扩展了先前不同的分析和计算结果的积累。

英文摘要:

A two-field model provides an unifying framework for elasticity, lattice dynamics and electromechanical coupling in graphene and carbon nanotubes, describes optical phonons, nontrivial acoustic branches, strain-induced gap opening, gap-induced phonon softening, doping-induced deformations, and even the hexagonal graphenic Brillouin zone, and thus explains and extends a previously disparate accumulation of analytical and computational results.
