对“用场发射电子显微镜成像碳原子链的原子轨道”一文的评论

Comment to "Imaging the atomic orbitals of carbon atomic chains with field-emission electron microscopy"

Nicola Manini, Giovanni Onida

摘要:

在线性原子链的场发射电子显微镜中观察到稳定的双峰图案需要破坏轴对称的稳定机制,这未被Mikhailovskij等人[Phys. Rev. B 80,165404(2009)]正确识别。使用微观计算,我们将观察到的图案归因于链连接的配体产生的对称性破缺,加上碳π键交替。

英文摘要:

The observation of a stable doublet pattern in the field-emission electron microscopy of a linear atomic chain requires a stable mechanism breaking the axial symmetry, which is not identified correctly by Mikhailovskij et al. [Phys. Rev. B 80, 165404 (2009)]. Using microscopic calculations, we attribute the observed pattern to the symmetry breaking produced by the ligand where the chain is attached, plus carbon pi-bonding alternation.
