氦原子层吸附在石墨表面作为二维理想量子系统之一,一直受到人们的关注。虽然以前的报告中子衍射显示在这些系统中的基本结构信息,仍然存在许多悬而未决的问题。在这里,我们提出了表面晶体截断棒(CTR)散射使用同步辐射X射线作为一种有前途的方法,揭示在低于2 K的温度下,在石墨上的氦膜的表面和界面结构,基于初步的实验结果单层ofHe薄石墨。我们对X射线辐射产生的热量的估计也表明,即使在接近100 mK的系统温度下,CTR散射也适用。
A few atomic layers of helium adsorbed on graphite have been attracting much attention as one of the ideal quantum systems in two dimension. Although previous reports on neutron diffraction have shown fundamental structural information in these systems, there still remain many open questions. Here, we propose surface crystal truncation rod (CTR) scatterings using synchrotron radiation X-rays as a promising method to reveal surface and interface structures of helium films on graphite at temperatures below 2 K, based on the preliminary experimental results on a monolayer ofHe on a thin graphite. Our estimation on heat generation by X-ray irradiations also suggests that CTR scatterings are applicable to even at system temperatures near 100 mK.
