论文摘要
量子厅标准的历史延伸了几十年，并且主要始于使用GAA，鉴于2D电子系统表现出有趣的量子现象。在2000年代末，对石墨烯等2D材料的研究变得普遍。观察到QHE，并迅速被计量学家使用。 QHR设备正在基于石墨烯，并通过化学蒸气沉积（CVD），外延生长和石墨的去角质进行制造。鉴于许多可用石墨烯合成的方法，正在进行寻找用于计量目的的最佳合成方法的努力。由于其原始的结晶度，剥落的石墨烯众所周知，它表现出最高的迁移率。就计量测试而言，这是主要的初始候选者。
The history of quantum Hall standards stretches several decades and mostly begins with the use of GaAs given that 2D electron systems exhibit interesting quantum phenomena. At the end 2000s, research in 2D materials like graphene became prevalent. The QHE was observed and quickly became accessible to metrologists. QHR devices were becoming graphene-based, with fabrications performed by chemical vapor deposition (CVD), epitaxial growth, and the exfoliation of graphite. Given the many methods of available graphene synthesis, efforts to find an optimal synthesis method for metrological purposes were underway. Exfoliated graphene was widely known to exhibit the highest mobilities due to its pristine crystallinity. It was a primary initial candidate as far as metrological testing was concerned.
