Geometry-Controlled Polarization Photocurrents in Scalable PtSe2 Infrared Pixels
Eunice Y. Paik, Owen A. Vail, Madaline R. Marland +11
Polarization-sensitive photodetectors provide multi-dimensional optical information beyond the capabilities of traditional intensity-based detectors. The noble metal dichalcogenide…
Enhanced detection of circularly polarized photons with topological materials
Hamideh Sharifpour, Avik W. Ghosh, George J. de Coster
Topological insulators (TI) are highly attractive platforms for next-generation optoelectronic and photonic devices. Spin-momentum locking of topological surface states enhances th…
Visible and Terahertz Nonlinear Responses in the Topological Noble Metal Dichalcogenide PdTe2
George J. de Coster, Lucas Lafeta, Stefan Heiserer +5
Nonlinear processes can offer pathways to next-generation sensors and frequency mixing devices to overcome modern imaging, detection, and communication challenges. In this article,…
Long-range Phase Coherence and Tunable Second Order -Josephson Effect in a Dirac Semimetal
Pranava K. Sivakumar, Mostafa T. Ahari, Jae-Keun Kim +6
Superconducting diode effects have recently attracted much attention for their potential applications in superconducting logic circuits. Several mechanisms such as magneto-chiral e…
Structural, electronic, and magnetic properties of CrTe2
Yuhang Liu, Sohee Kwon, George J. de Coster +2
Two-dimensional chromium ditelluride (CrTe2) is a promising ferromagnetic layered material that exhibits long-range ferromagnetic ordering in the monolayer limit. The formation ene…
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…
Magnetic-field-free nonreciprocal transport in graphene multi-terminal Josephson junctions
Fan Zhang, Asmaul Smitha Rashid, Mostafa Tanhayi Ahari +6
Nonreciprocal superconducting devices have attracted growing interest in recent years as they potentially enable directional charge transport for applications in superconducting qu…
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…
Low power In Memory Computation with Reciprocal Ferromagnet/Topological Insulator Heterostructures
Hamed Vakili, Samiran Ganguly, George J. de Coster +2
The surface state of a 3D topological insulator (3DTI) is a spin-momentum locked conductive state, whose large spin hall angle can be used for the energy-efficient spin orbit torqu…
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…
