Thermal and Adhesive Properties of Quench Condensed Bismuth Thin Films

About the Event

Quench-condensed (QC) bismuth thin films, deposited at low or cryogenic substrate temperatures Ts are known to exhibit superconductivity. However, the origin of this phenomenon is still debated. Over the last three years using characterization tools at NCFL, MCL and Holden Hall the work to understand crystallographic and thermal properties of the films has been done.  The work produced discoveries of texture evolution, self-assembly of bismuth scrolls and confined growth effects.

Yulia Kirina is a Ph.D. student in her third year at Virginia Tech, in the Materials Science and Engineering Department, under Dr. Kodambaka, Dr. Soghomonian and Dr. Heremans. She completed her bachelor's degree in Materials Science and Engineering in 2023. Yulia has been a user at the NCFL since 2019, making her one of the most veteran users in the facility. Currently her research focuses on characterization of bismuth thin films under different deposition conditions and on different substrates with the goal to understand reasons for superconductivity of Bi.
