Spin Hall conductivity in BiSb as an experimental test of bulk-boundary correspondence
Yongxi Ou, Wilson Yanez-Parreño, Yu-sheng Huang +9
Bulk-boundary correspondence is a foundational principle underlying the electronic band structure and physical behavior of topological quantum materials. Although it has been rigor…
Epitaxial growth and characterization of BiSb thin films on (0001) sapphire substrates
Yu-Sheng Huang, Saurav Islam, Yongxi Ou +4
We report the molecular beam epitaxy of Bi_1-xSb_x thin films () on (0001) sapphire substrates using a thin (Bi,Sb)Te buffer layer. Characterization of the…
Fast and Facile Synthesis Route to Epitaxial Oxide Membrane Using a Sacrificial Layer
Shivasheesh Varshney, Sooho Choo, Liam Thompson +7
The advancement in thin-film exfoliation for synthesizing oxide membranes has opened up new possibilities for creating artificially-assembled heterostructures with structurally and…
Robust negative longitudinal magnetoresistance and spin-orbit torque in sputtered Pt3Sn topological semimetal
Delin Zhang, Wei Jiang, Hwanhui Yun +11
Contrary to topological insulators, topological semimetals possess a nontrivial chiral anomaly that leads to negative magnetoresistance and are hosts to both conductive bulk states…
Thin film growth of the Weyl semimetal NbAs
Wilson Yanez, Yu-Sheng Huang, Supriya Ghosh +5
We report the synthesis and characterization of thin films of the Weyl semimetal NbAs grown on GaAs (100) and GaAs (111)B substrates. By choosing the appropriate substrate, we can…
Mending Cracks in Rutile TiO with Electron Beam
Silu Guo, Hwanhui Yun, Sreejith Nair +2
Restructuring of rutile TiO under electron beam irradiation driven by radiolysis was observed and analyzed using a combination of atomic-resolution imaging and electron energ…
