Nonlocal transport signatures of Andreev bound states Open
In this PhD thesis, quantum devices based on molecular-beam epitaxy grown InAs semiconductor with an in-situ grown epitaxial Al film were investigated. Novel device geometries were realized that allow for the study of bound states that eme…

Spin-resolved spectroscopy using a quantum dot defined in InAs 2DEG Open
We realize a device, based on InAs two-dimensional electron gas proximitized by superconducting Al, which allows a single quantum dot level to be used as a spectrometer of the density of states in a nanowire. Applying a magnetic field para…

Nonlocal signatures of hybridization between quantum dot and Andreev bound states Open
We investigate local and nonlocal signatures of hybridization between a quantum dot state and an extended Andreev bound state (ABS) in a gate-defined InAs nanowire with multiple side probes. When a quantum dot in one of the side probes was…

Nonlocal conductance spectroscopy of Andreev bound states in gate-defined InAs/Al nanowires Open
The charge character of Andreev bound states (ABSs) in a three-terminal semiconductor-superconductor hybrid nanowire was measured using local and nonlocal tunneling spectroscopy. The device is fabricated using an epitaxial InAs/Al two-dime…

Closing of the induced gap in a hybrid superconductor-semiconductor nanowire Open
Hybrid superconductor-semiconductor nanowires are predicted to undergo a\nfield-induced phase transition from a trivial to a topological superconductor,\nmarked by the closure and re-opening of the excitation gap, followed by the\nemergenc…

Measurement circuit effects in three-terminal electrical transport measurements Open
In this article we study measurement circuit effects in three-terminal electrical transport measurements arising from finite line impedances. We provide exact expressions relating the measured voltages and differential conductances to thei…
