In this paper, we observed intrinsic magnetic topological insulators MnBi2-xSbxTe4 (MBST) with STM/STS and quasiparticle interference. We presented a statistical analysis of the nanoscale effect of defects to identify (Bi,Sb)Mn anti-site defects to be the main source of the observed doping fluctuations, leading towards the formation of nanoscale charge puddles and effectively closing the transport gap.
[2023/9] Chris Howard won the 3rd place prize for the Q3 Lab Safety Culture Awards. Congratulations!

In this paper, we probed unconventional superconductivity of FeSe using Andreev reflection between STM tip and superconductor sample. The decay constant spectroscopy reveals that Andreev reflection inside the superconducting gap of FeSe fits best to the d-wave pairing symmetry.
[2023/8] We welcome a new undergraduate student, Conner Vernachio!
