WebExplore 223 research articles published on the topic of “Cooper pair” in 2024. Over the lifetime, 4825 publication(s) have been published within this topic receiving 101244 citation(s). WebWe find that InSb nanowires coupled to tin exhibit a hard induced superconducting gap with a magnitude of up to 700 µeV. Superconductivity persists to magnetic fields up to 4 Tesla for 15 nm thick Sn shells. Islands of tin do exhibit 2e-periodic charging patterns, where e is the elementary charge. These results are obtained even though Sn and InSb

WebNov 2, 2024 · Due to the energy level repulsion of the valence and conduction bands, the gap is closed and the bands across the Fermi energy are inverted. In this way, the 2-layer DLHC GaAs becomes a topological insulator with Z 2 = 1. Similar topological properties are also found in other 2-layer DLHC materials like InSb, InAs, GaSb, HgTe, and AlSb [30,44].
