Advanced synthesis of semiconductor nanowires (NWs) enables their application in diverse fields, notably in chemical and electrical sensing, photovoltaics, or quantum electronic devices. In particular, indium arsenide (InAs) NWs are an ideal platform for quantum devices, e.g. they may host topological Majorana states. While the synthesis has been continously perfected, only a few techniques have been developed to tailor individual NWs after growth. Here we present three wet chemical etch…

Engineering a topological quantum dot device through planar magnetization in bismuthene
The discovery of quantum spin Hall materials with huge bulk gaps in experiment, such as bismuthene, provides a versatile platform for topological devices. We propose a topological quantum dot (QD)
Constant-rate dissolution of InAs nanowires in radiolytic water observed by in situ liquid cell TEM.
The kinetics of InAs NW dissolution in radiolytic water is investigated by analyzing the source supply, surface reaction and product diffusion steps in the dissolution process and surface reaction limited dissolution fits well with the experimental results and the activation energy should be constant during the whole dissolution process.

Minimization of the contact resistance between InAs nanowires and metallic contacts
Different processes for optimizing the formation of Ohmic contacts to InAs nanowires are investigated and an upper bound of 1.4 × 10(-7) Ω cm(2) for the contact resistivity of metallic contacts on nanowire treated by the argon milling process is extracted.
Gigahertz Quantized Charge Pumping in Bottom-Gate-Defined InAs Nanowire Quantum Dots.
Charge pumping in InAs NWs is relevant not only in metrology as a current standard, but also opens up the opportunity to investigate a variety of exotic states of matter, for example, Majorana modes by single electron spectroscopy and correlation experiments.

Epitaxial growth of heterostructure nanowires allows for the definition of narrow sections with specific semiconductor composition. The authors demonstrate how postgrowth engineering of III-V

The obtained nanogaps in InAs wires have potential as semiconducting electrodes to investigate electronic transport in nanoscale objects by dielectrophoretically trapping 30 nm diameter gold nanoparticles into the gap.
Epitaxy of semiconductor-superconductor nanowires.
The grain growth kinetics of the metal phase is formulated in general terms of continuum parameters and bicrystal symmetries and seems to solve the soft-gap problem in superconducting hybrid structures.
Self-aligned charge read-out for InAs nanowire quantum dots.
A highly sensitive charge detector is realized for a quantum dot in an InAs nanowire and charge stability diagrams measured by transport through the quantum dot and charge detection merge perfectly.
Method for suppression of stacking faults in Wurtzite III-V nanowires.
The suppression of the number of stacking faults was obtained by a procedure within the vapor-liquid-solid growth, which exploits the theoretical result that nanowires of small diameter adopt purely wurtzite structure and are observed to thicken once the axial growth exceeds a certain length.

We have studied the formation of ohmic contacts to InAs nanowires by chemical etching and passivation of the contact areas in an ammonium polysulfide, (NH4)2Sx, water solution. The nanowires were
