About Paper:

In condensed matter physics, a moiré material is created by stacking two or more layers of two-dimensional (2D) materials with an interlayer rotation. The interference effect between atomic lattices of the constituent layers gives rise to a moiré pattern, an artificial and much larger lattice. The presence of the moire superlattice can strongly modify the electronic properties in the material, giving rise to novel quantum electronic phases, such as unconventional superconductivity, topological insulators etc. To search for new quantum phases of electrons in this platform, we designed devices consisting of moire transition metal dichalcogenide (TMD) as a core layer and other functional 2D material as supporting layers. Multiple devices were successfully fabricated using Van der Waals dry transfer technique and the following lithography steps. We will study the novel superconducting phase and fractional Chern insulators in these devices at an extremely low temperature of 250 mK.
