Milli Kelvin-STM Studies on correlated electron systems

Understanding the mechanism of unconventional superconductivity in correlated electron materials is a step towards developing superconductors with higher transition temperatures. Scanning tunneling microscopy/spectroscopy is a perfect tool to study the quantum mechanical states of correlated electron materials both in real space and momentum space. In this taIk, I will discuss about an spectroscopic imaging scanning tunneling microscopy (SI-STM) which operates at milli-Kelvin temperatures, and magnetic fields up to 14 Tesla. Measuring at ultra low temperatures has the advantage of approaching exciting electronic phases (e.g. superconductivity), and additionally enhances the spectroscopic energy resolution to microelectron volt range, which is crucial for the study of strongly correlated electron materials. I will show results of different families of correlated electron materials, in particular about their superconducting and magnetic phases. The studied superconductors belong to the family of heavy fermion compounds (CeCu2Si2), and noncentrosymmetric superconductors (BiPd); whereas the magnetic compounds are linked with parent compounds of iron-based superconductors (Fe1+yTe). The results can help to further understand the relation and interplay between magnetism and superconductivity, and also the mechanism of superconductivity in these materials.
