Spintronic Quantum Phase Transition in a Heterostructure with Giant Rashba Spin-Orbit Coupling
Jennifer E. DeMell, Ivan Naumov, Gregory M. Stephen +10
Mechanical stacking of two dissimilar materials often has surprising consequences for heterostructure behavior. In particular, a two-dimensional electron gas (2DEG) is formed in th…
Emergence of Three-fold Symmetric Helical Photocurrents in Epitaxial Low Twinned BiSe
Blair C. Connelly, Patrick J. Taylor, George J. de Coster
We observe enhanced three-fold symmetric helicity-dependent topological photocurrents using time-domain THz spectroscopy in epitaxially-grown Bi2Se3 with reduced crystallographic t…
Magnetotransport in graphene/Pb0.24Sn0.76Te heterostructures: finding a way to avoid catastrophe
Gregory M. Stephen, Ivan Naumov, Nicholas A. Blumenschein +9
While heterostructures are ubiquitous tools enabling new physics and device functionalities, the palette of available materials has never been richer. Combinations of two emerging…
Strain-tunable Berry curvature in quasi-two-dimensional chromium telluride
Hang Chi, Yunbo Ou, Tim B. Eldred +22
Magnetic transition metal chalcogenides form an emerging platform for exploring spin-orbit driven Berry phase phenomena owing to the nontrivial interplay between topology and magne…
Experimental detection of surface spin-polarized electron accumulation in topological insulators using scanning tunneling microscopy
S. Tyagi, M. Dreyer, D. Bowen +6
Spin-momentum locking in the surface mode of topological insulators (TI) leads to the surface accumulation of spin-polarized electrons caused by bias current flows through TI sampl…
Study Of Surface Spin-Polarized Electron Accumulation In Topological Insulators Using Scanning Tunneling Microscopy
S. Tyagi, M. Dreyer, D. Bowen +6
The results of scanning tunneling microscopy experiments using iron-coated tungsten tips and current-carrying bismuth selenide () samples are reported. Asymmetry in tunne…
Growth and Magnetotransport in Thin Film α-Sn on CdTe
Owen Vail, Patrick Taylor, Patrick Folkes +2
We report growth and characterization of epitaxial -Sn thin films grown on CdTe(111)B. Noninvasive techniques verify the film's pseduomorphic growth before fabrication of magnet…
Weak-link Josephson Junctions Made from Topological Crystalline Insulators
R. A. Snyder, C. J. Trimble, C. C. Rong +3
We report on the fabrication of Josephson junctions using the topological crystalline insulator PbSnTe as the weak link. The properties of these junctions are chara…
