Promoting spin-polarized states in Bi/Si(111) interface mediated by Ba intercalation for advanced spintronics applications

Emergence of quasi-1D spin-polarized states in ultrathin Bi films on InAs(111)A for spintronics applications

“…The discovery, characterization and control of electronic properties in low-dimensional materials reduced down to the atomic-scale limit are of special interest for nanoelectronics due to a number of fascinating effects such as unconventional superconductivity, 1 non-trivial topology, 2 flat bands, 3 the topological Hall effect, 4 strong spin–orbit coupling effects induced by the integration of heavy quasiparticles 5 or interface engineering, 6,7 highly anisotropic spin-polarized states 8–10 and other emergent effects promising for versatile applications in the nanotechnology industry. 11–13 It is noteworthy that spin–orbit coupling (SOC) plays a decisive role in many electronic effects observed in quantum materials.…”
