摘要:

由单排sp-杂化碳制成的线性链被预测显示出迷人的机械电子性质,与它们在现实碳结构中的终止和稳定有关。目前的工作描述了如何计算的振动性质的累积和多炔碳链允许一个解释的碳炔的功能观察到的簇组装的sp-sp2膜的拉曼光谱。整体情况与空气或氧气暴露引起的sp组分的测量衰减一致。

英文摘要:

Linear chains made by a single row of sp-hybridized carbon are predicted to display fascinating mechano-electronic properties connected with their termination and stabilization inside realistic carbon structures. The present work describes how the computed vibrational properties of cumulenic and polyynic carbon chains allow one to interpret the carbynic features observed in Raman spectra of cluster-assembled sp-sp2 films. The overall picture is consistent with the measured decay of the sp components induced by air or oxygen exposure.
