石墨层间结合的性质和强度

The nature and strength of inter-layer binding in graphite

Leonardo Spanu, Sandro Sorella, Giulia Galli

摘要:

我们用从头算多体理论计算了石墨的层间成键性质。我们进行了变分和扩散量子蒙特卡罗计算,发现了与最新实验完全一致的平衡层间结合能。我们还分析了总能量的行为作为一个功能的层间分离在大的距离比较的结果与无规相近似的预测。

英文摘要:

We computed the inter-layer bonding properties of graphite using an ab-initio many body theory. We carried out variational and diffusion quantum Monte Carlo calculations and found an equilibrium inter-layer binding energy in good agreement with most recent experiments. We also analyzed the behavior of the total energy as a function of interlayer separation at large distances comparing the results with the predictions of the random phase approximation.
