(author), Kölling, S. (author), Verheijen, M.P.A.M. (author), Bakkers, E.P.A.M. (author), Kouwenhoven, Leo P. (author)Low dimensional semiconducting structures with strong spin-orbit interaction (SOI) and induced superconductivity attracted great interest in the search for topological superconductors. Both the strong SOI and hard superconducting gap are directly related to the topological protection of the predicted Majorana bound states. Here we explore the...journal article 2018

(author), Nguyen, Binh Minh (author), Kouwenhoven, Leo P. (author)The spin-orbit interaction is investigated in a dual gated InAs/GaSb quantum well. Using an electric field, the quantum well can be tuned between a single-carrier regime with exclusively electrons as carriers and a two-carrier regime where electrons and holes coexist. The spin-orbit interaction in both regimes manifests itself as a beating in...journal article 2017

(author), Kouwenhoven, Leo P. (author)Transport measurements in inverted InAs/GaSb quantum wells reveal a giant spin-orbit splitting of the energy bands close to the hybridization gap. The splitting results from the interplay of electron-hole mixing and spin-orbit coupling, and can exceed the hybridization gap. We experimentally investigate the band splitting as a function of top...journal article 2017
