Subband occupation in semiconductor-superconductor nanowires
Benjamin D. Woods, Sankar Das Sarma, Tudor D. Stanescu
Subband occupancy (i.e. the number of occupied subbands or energy levels in the semiconductor) is a key physical parameter characterizing the topological properties of superconduct…
Electronic structure of full-shell InAs/Al hybrid semiconductor-superconductor nanowires: Spin-orbit coupling and topological phase space
Benjamin D. Woods, Sankar Das Sarma, Tudor D. Stanescu
We study the electronic structure of full-shell superconductor-semiconductor nanowires, which have recently been proposed for creating Majorana zero modes, using an eight-band $\ve…
Presence versus absence of end-to-end nonlocal conductance correlations in Majorana nanowires: Majorana bound states versus Andreev bound states
Yi-Hua Lai, Jay D. Sau, Sankar Das Sarma
By calculating the differential tunneling conductance spectra from the two ends of a Majorana nanowire with a quantum dot embedded at one end, we establish that a careful examinati…
