The research aims to understand the impact of crystalline quality on spin–orbit coupling in bismuth thin films.
Used molecular beam epitaxy to grow Bi thin films on Si(111) substrates.
Examined electronic transport properties under various magnetic fields.
Analyzed weak anti-localization and planar Hall response at room temperature.
Showed robust spin–orbit coupling with weak anti-localization features under magnetic fields.
Observed a planar Hall response indicative of Rashba-type SOC.
Found a temperature-driven sign reversal in Hall carrier concentration, suggesting a transition in carrier type.
