Basal-plane growth of cadmium arsenide by molecular beam epitaxy
David A. Kealhofer, Honggyu Kim, Timo Schumann +3
(001)-oriented thin films of the three-dimensional Dirac semimetal cadmium arsenide can realize a quantum spin Hall insulator and other kinds of topological physics, all within the…
Absence of signatures of Weyl orbits in the thickness dependence of quantum transport in cadmium arsenide
Luca Galletti, Timo Schumann, David A. Kealhofer +2
In a Weyl orbit, the Fermi arc surface states on opposite surfaces of the topological semimetal are connected through the bulk Weyl or Dirac nodes. Having a real-space component, t…
Bulk-Free Topological Insulator Bi2Se3 nanoribbons with Magnetotransport Signatures of Dirac Surface States
Gunta Kunakova, Luca Galletti, Sophie Charpentier +6
Many applications for topological insulators (TIs) as well as new phenomena require devices with reduced dimensions. While much progress has been made to realize thin films of TIs…
