Topological quantum computing is based on braiding of Majorana zero modes encoding topological qubits. A promising candidate platform for semiconductor-superconductor hybrid nanowires. The realization qubits and operations requires scalable disorder-free nanowire networks. Selective area growth in-plane InAs InSb nanowires, together with shadow-wall superconductor structures, have demonstrated this scalability by achieving various network structures. However, the noticeable lattice mismatch...
Hybrid semiconductor-superconductor InAs-Al nanowires with uniform and defect-free crystal interfaces are one of the most promising candidates used in quest for Majorana zero modes (MZMs). However, InAs often exhibit a high density randomly distributed twin defects stacking faults, which result an uncontrolled non-uniform interface. Furthermore, this type disorder can create potential inhomogeneity wire, destroy topological gap, form trivial sub-gap states mimicking MZM transport...
PbTe nanowires coupled to a superconductor have recently been proposed as potential Majorana platform. The hallmark of the one-dimensional nature ballistic is their quantized conductance.

Semiconductor nanowires coupled to a superconductor provide powerful testbed for quantum device physics such as Majorana zero modes and gate-tunable hybrid qubits. The performance of these devices heavily relies on the quality induced superconducting gap. A hard gap, evident vanishing subgap conductance in tunneling spectroscopy, is both necessary desired. gap has been achieved extensively studied before III–V semiconductor (InAs InSb). In this study, we present observation PbTe Pb. size Δ ∼...

We report phase coherent electron transport in PbTe nanowire networks with a loop geometry. Magneto-conductance shows Aharonov-Bohm (AB) oscillations periods of $h/e$ and $h/2e$ flux. The amplitude is enhanced near zero magnetic field, possibly due to interference between time-reversal paths. Temperature dependence the AB amplitudes suggests coherence length $\sim$ 8 - 12 $\mu$m at 50 mK. This scale larger than typical geometry PbTe-based hybrid semiconductor-superconductor devices.
Disorder is the primary obstacle in current Majorana nanowire experiments. Reducing disorder or achieving ballistic transport thus of paramount importance. In clean and devices, quantized conductance expected, with plateau quality serving as a benchmark for assessment. Here, we introduce PbTe devices grown by using selective-area-growth (SAG) technique. Quantized plateaus units 2e2/h are observed at zero magnetic field. This observation represents an advancement diminishing within SAG...
At sufficiently low temperatures, many quantum effects, such as weak localization, electron-electron interaction (EEI), and Kondo screening, can lead to pronounced corrections the semiclassical electron transport. Although temperature longitudinal resistivity, ordinary Hall or anomalous (AH) resistivity are often observed, three of them have never been simultaneously detected in a single sample. Here, we report on observation $\sqrt{T}$-type dependences longitudinal, AH resistivities at...
