Pre-Patterned Superconducting Contacts for Clean Superconductor-Topological Material Interfaces Enabling Long-Range Josephson Coupling
Yong-Bin Choi, Chang-Won Choi, Luke Holtzman +8
Phase-coherent superconducting proximity in topological materials requires clean superconductor-topological material (SC-TM) interfaces, yet conventional top-contact fabrication of…
Unveiling three types of fermions in a nodal ring topological semimetal through magneto-optical transitions
Jiwon Jeon, Taehyeok Kim, Jiho Jang +5
We investigate the quasiparticles of a single nodal ring semimetal SrAs through axis-resolved magneto-optical measurements. We observe three types of Landau levels scaling as $…
Optical transitions of a single nodal ring in SrAs: radially and axially resolved characterization
Jiwon Jeon, Jiho Jang, Hoil Kim +7
SrAs is a unique nodal-line semimetal that contains only a single nodal ring in the Brillouin zone, uninterrupted by any trivial bands near the Fermi energy. We performed axis-…
Electrical detection of spin-polarized current in topological insulator Bi1.5Sb0.5Te1.7Se1.3
Tae-Ha Hwang, Hong-Seok Kim, Hoil Kim +2
Spin-momentum locked (SML) topological surface state (TSS) provides exotic properties for spintronics applications. The spin-polarized current, which emerges owing to the SML, can…
