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.

二维（2D）的材料研究已经在2004年的第一个2D材料的分离中出现。石墨烯是排列在蜂蜜梳子晶格中的单个原子厚的碳原子。由于其特性的特性，它被认为是不同广泛应用的潜在材料。它是已知的最薄，最强的材料，它是透明的，并且电力比铜更好。它对气体和液体完全不渗透，并且非常灵活。在过去的几年中，科学界正在大力研究从分层材料（包括绝缘体，半导体和超导体）中的另一个原子厚的平面的制造。这些具有多种特性的新2D材料的可用性为材料设计和工程学开辟了许多可能的机会。例如，通过将不同的2D原子片堆叠在所需的序列上，将导致形成具有新型特性的新的三维材料。最近，曼彻斯特小组通过将石墨烯与半导体的钼二硫化物结合起来来证明了这一概念，以制造一种新型的垂直晶体管。通过这种初始结果，我的特别兴趣是用类似于高温层的超导体的结构来制造新型的分层材料。超导性是零电阻和完全驱动磁场的现象。在高温超导体（HTS）中，超导性是由形成HTS晶体的原子的交替层和绝缘原子层产生的。借助不同的2D晶体，我设想通过将不同的2D晶体彼此堆叠来设计具有相似结构的材料。寻找HTS是一个雄心勃勃的项目，但是如果我成功地基于这些新颖的材料制作HT，这可能会引起极大的兴趣。
