结构无序对石墨量子振荡的影响

Effect of structural disorder on quantum oscillations in graphite

Bruno Camargo, Yakov Kopelevich, Steven Hubband, Alan Usher

摘要:

我们研究了在温度低至30 mK和磁场高至14 T的条件下,结构无序对单晶和高取向热解石墨样品中测得的de Haas van Alphen(dHvA)和Shubnikov de Haas(SdH)量子振荡的影响。的测量进行了不同的样品,其特征在于通过X射线衍射,透射电子显微镜和原子力显微镜技术。我们的结果揭示了量子振荡的振幅和表面粗糙度之间的相关性。

英文摘要:

We have studied the effect of structural disorder on the de Haas van Alphen (dHvA) and Shubnikov de Haas (SdH) quantum oscillations measured in single-crystal and highly oriented pyrolytic graphite samples at temperatures down to 30 mK and at magnetic fields up to 14 T. The measurements were performed on different samples characterized by means of x-ray diffraction, transmission electron microscopy and atomic-force microscopy techniques. Our results reveal a correlation between the amplitude of quantum oscillations and the surface roughness.
