In this paper, we observed the interaction between topological surface states and Rashba edge states as manifested on step edges of Bi2<\/sub>Se3<\/sub> thin films. The Rashba edge states appear\/disappear depending on the thickness of the film due to their interaction with the bottom topological surface states.<\/p>\n\n\n\n

[2024\/06]<\/strong> We welcome summer undergraduate students, Courtnei Powell<\/strong><\/em> and Andrew Lee<\/strong><\/em>.<\/p>\n\n\n\n

Courtnei and Andrew, mentored by Chris, will work on the UT-ORII SMaRT project<\/strong> that focuses on quasiparticle interference analysis with machine learning.<\/strong><\/p>\n\n\n\n

[2024\/05]<\/strong> New Unisoku USM-1300 STM<\/strong> has been successfully installed and running.<\/p>\n\n\n\n

We appreciate everyone’s effort, including Unisoku<\/strong> and SPECS people<\/strong>!<\/p>\n\n\n\n

In this paper, we observed intrinsic magnetic topological insulators MnBi2-x<\/sub>Sbx<\/sub>Te4<\/sub> (MBST) with STM\/STS and quasiparticle interference. We presented a statistical analysis of the nanoscale effect of defects to identify (Bi,Sb)Mn<\/sub> 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.<\/p>\n\n\n\n

[2023\/9]<\/strong> Chris <\/strong>won the 3rd place prize<\/strong><\/em> for the “Q3 Lab Safety Culture Awards<\/strong><\/em>“. Congratulations!<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

[2023\/8]<\/strong> We welcome a new undergraduate student, Conner Vernachio<\/strong><\/em>.<\/p>\n\n\n\n

[2023\/7]<\/strong> We welcome a new postdoc, Wooin Yang<\/strong><\/em>. He will jointly work at both UTK and ORNL.<\/p>\n\n\n\n

[2022\/8]<\/strong> We are starting a new lab in the University of Tennessee, Knoxville<\/strong>!<\/p>\n\n\n\n

Our new lab will be located in the Institute of Advanced Materials and Manufacturing (IAMM) building. The new ultra-low-temperature STM is coming soon!<\/p>\n<\/div>\n<\/div>\n\n\n\n
