This proposal is driven by our recent discovery of superconductivity in C6Ca and C6Yb. The pairing mechanism in these materials is yet to be established, and thus understanding the excitation spectrum will be of central importance and requiring a variety of techniques. The relationship of the electronic properties and structure is crucial for the elucidation of elevated transition temperatures and the onset of valence instabilities. Therefore a significant part of our studies will focus on the crystal and electronic structure and how these tune with parameters such as pressure and dimensionality. Furthermore, working with intercalated materials has made us aware of the potential of novel graphitic superconducting nano-structures and devices. We propose to explore two such engineered structures.

这一提议是由我们最近在C6Ca和C6Yb中发现的超导电性推动的。这些材料中的配对机制尚未建立，因此了解激发光谱将是至关重要的，需要各种技术。电子性质和结构的关系对于解释转变温度升高和价不稳定的开始至关重要。因此，我们的大部分研究将集中在晶体和电子结构，以及这些结构如何与压力和维度等参数相协调。此外，对插层材料的研究使我们意识到了新型石墨超导纳米结构和器件的潜力。我们建议探索两个这样的工程结构。
