WebUsing a combination of reflectivity and ellipsometry, we determined the far-infrared dielectric functions of molecular beam epitaxy-grown Hg 1−x Cd x Se thin films between 85 cm −1 and 8, 000 cm −1.Spectroscopic ellipsometry, performed between 400 cm −1 and 8000 cm −1, recovered the dielectric function and the thickness of each film. ... WebIn this work we present the self-consistent determination of the spin-orbit coupling constant in heterostructure with two subbands.As recently proposed, the effective hamiltonian for the conduction band in the effective mass approximation contains an inter-subband spin-orbit coupling which is non-zero even for symmetric heterostructures.
Web23 mrt. 2024 · Nonmagnetic chiral crystals are a new class of systems hosting Kramers–Weyl Fermions, arising from the combination of structural chirality, spin–orbit coupling (SOC), and time-reversal symmetry. These materials exhibit nontrivial Fermi surfaces with SOC-induced Chern gaps over a wide energy range, leading to exotic … WebCurrently, the members of the group are Xavier Bonet Monroig, Álvaro Donís Vela, Alicja Dutkiewicz, Matthias Flór, Gal Lemut, Dmytro Oriekhov, Stephan Plugge, Stefano Polla, Tereza Vakhtel, and Vladimir Zakharov.
