Terahertz time-domain signatures of the inverse Edelstein effect in topological-insulator|ferromagnet heterostructures
Genaro Bierhance, Chihun In, Enzo Rongione +14
Three-dimensional topological insulators possess topologically protected surface states with spin-momentum locking, which enable spin-charge-current interconversion (SCI) by the in…
Interplay between altermagnetic order and crystal symmetry probed using magnetotransport in epitaxial altermagnet MnTe
Himanshu Bangar, Polychronis Tsipas, Prasanna Rout +5
Altermagnets are a new class of magnetic materials characterized by fully compensated spins arranged in alternating local structures, allowing for spin-split bands similar to those…
Excited States Band Mapping and Ultrafast Nonequilibrium Dynamics in Topological Dirac Semimetal 1T-ZrTe
Sotirios Fragkos, Evgenia Symeonidou, Emile Lasserre +7
We performed time- and polarization-resolved extreme ultraviolet momentum microscopy on topological Dirac semimetal candidate 1T-ZrTe. Excited states band mapping uncovers the…
Exploiting the close-to-Dirac point shift of Fermi level in Sb2Te3/Bi2Te3 topological insulator heterostructure for spin-charge conversion
E. Longo, L. Locatelli, P. Tsipas +5
Properly tuning the Fermi level position in topological insulators is of vital importance to tailor their spin-polarized electronic transport and to improve the efficiency of any f…
Engineering heat transport across epitaxial lattice-mismatched van der Waals heterointerfaces
Emigdio Chavez-Angel, Polychronis Tsipas, Peng Xiao +6
Artificially engineered 2D materials offer unique physical properties for thermal management, surpassing naturally occurring materials. Here, using van der Waals epitaxy, we demons…
Large spin-to-charge conversion at room temperature in extended epitaxial Sb2Te3 topological insulator chemically grown on Silicon
Emanuele Longo, Matteo Belli, Mario Alia +8
Spin-charge interconversion phenomena at the interface between magnetic materials and topological insulators (TIs) are attracting enormous interest in the research effort towards t…
Molecular Beam Epitaxy of thin HfTe2 semimetal films
Sigiava Aminalragia-Giamini, Jose Marquez-Velasco, Polychronis Tsipas +3
Epitaxial thin films of 1T-HfTe2 semimetal are grown by MBE on AlN(0001) substrates. The measured in-plane lattice parameter indicates an unstrained film which is also azimuthally…
