Assembly, X-ray diffraction and electronic transport measurement of atomically thin Bi2Sr2CaCu2O8+y high temperature superconducting van der Waals cuprate heterostructures
Abstract
Unique physical properties of low-dimensional electronic systems arise from the fine balance and interplay of often competing phenomena in the reduced dimensionality. We fabricated van der Waals heterostructure based on atomically thin Bi2Sr2CaCu2O8+y (BSCCO) high temperature superconductor. Unlike conventional superconductors, atomically thin BSCCO film exhibits an intrinsic multi-scale heterogeneity and a complete new set of imaging and nanofabrication tools are required to tame this complexity. In this talk, we will show the structural nanoscale heterogeneity using advanced X-ray nanoprobes of an assembled few-unit cells van der Waals cuprate high temperature superconducting heterostructure. Towards the end, I will demonstrate our recent realization of Josephson junctions made of assembled van der Waals cuprate heterostructures.
