项目摘要

Two dimensional (2D) material research has emerged with the isolation of the first 2D material named graphene, in 2004. Graphene is a single atom thick sheet of carbon atoms arranged in a honey comb lattice. It is considered as a potential material for different wide-ranging applications because of its exceptional properties. It is the thinnest and strongest material known and it is transparent and conducts electricity even better than copper. It is completely impermeable to gases and liquids and extremely flexible. For the last few years, the scientific community was heavily looking into the fabrication of other one atom thick planes from layered materials, including insulators, semiconductors and superconductors. The availability of these new 2D materials with diverse properties opens up many possible opportunities in materials design and engineering. For example, by stacking different 2D atomic sheets on top of each other in a desired sequence will result in the formation of new three dimensional materials with novel properties. Recently, the Manchester group demonstrated this concept by combining graphene with semiconducting molybdenum disulfide to fabricate a new type of vertical transistors.Motivated by this initial result, my particular interest is to fabricate novel layered materials with structures similar to that of high temperature layered superconductors. Superconductivity is a phenomenon of zero electrical resistance and complete expulsion of magnetic field. In high temperature superconductors (HTS), superconductivity arises from the alternating layers of conducting and insulating layers of atoms, which form the HTS crystal. With the availability of different 2D crystals, I envisage to design materials with a similar structure by stacking different 2D crystals on top of each other. The search for HTS is an ambitious project, but if I am successful in making HTS based on these novel materials, this could spark massive interest.

2004 年，随着第一种二维材料石墨烯的分离，二维 (2D) 材料研究随之兴起。石墨烯是排列成蜂巢晶格的单原子厚碳原子片。由于其卓越的性能，它被认为是一种具有广泛应用前景的材料。它是已知最薄、最强的材料，透明且导电性甚至比铜更好。它完全不渗透气体和液体，并且非常柔韧。在过去的几年里，科学界一直在大力研究用层状材料（包括绝缘体、半导体和超导体）制造其他单原子厚平面。这些具有多种特性的新型二维材料的出现为材料设计和工程带来了许多可能的机会。例如，通过按所需顺序将不同的二维原子片堆叠在一起，将形成具有新颖特性的新三维材料。最近，曼彻斯特小组通过将石墨烯与半导体二硫化钼结合来制造新型垂直晶体管来展示了这一概念。受这一初步结果的启发，我特别感兴趣的是制造结构类似于高温层状超导体的新型层状材料。超导是一种零电阻和完全排除磁场的现象。在高温超导体 (HTS) 中，超导性源自原子的导电层和绝缘层的交替层，形成了 HTS 晶体。随着不同二维晶体的出现，我设想通过将不同的二维晶体堆叠在一起来设计具有相似结构的材料。寻找高温超导是一个雄心勃勃的项目，但如果我成功地基于这些新颖材料制造出高温超导，这可能会激发人们的巨大兴趣。
