With the rise of quantum computing and recent experiments into topological quantum computers come exciting new opportunities for III-V semiconductor quantum nanostructures. In this thesis, we explore the scalable fabrication of patterned arrays and branche ...

Selective-area epitaxy provides a path toward high crystal quality, scalable, complex nanowire networks. These high-quality networks could be used in topological quantum computing as well as in ultrafast photodetection schemes. Control of the carrier densi ...

The growth of compound semiconductors on silicon has been widely sought after for decades, but reliable methods for defect-free combination of these materials have remained elusive. Recently, interconnected GaAs nanoscale membranes have been used as templa ...

The nature of the liquid-solid interface determines the characteristics of a variety of physical phenomena, including catalysis, electrochemistry, lubrication, and crystal growth. Most of the established models for crystal growth are based on macroscopic t ...

Here, we present a two-step annealing procedure to imprint nanofeatures on SiO2 starting from metallic microfeatures. The first annealing transforms the microfeatures into gold nanoparticles and the second imprints these nanoparticles into the SiO2 layer w ...

Selective area epitaxy (SAE) provides the path for scalable fabrication of semiconductor nanostructures in a device-compatible configuration. In the current paradigm, SAE is understood as localized epitaxy, and is modelled by combining planar and self-asse ...

Nanoscale membranes have emerged as a new class of vertical nanostructures that enable the integration of horizontal networks of III-V nanowires on a chip. To generalize this method to the whole family of III-Vs, progress in the understanding of the membra ...

Zn3As2 is a promising earth‐abundant semiconductor material. Its bandgap, around 1 eV, can be tuned across the infrared by alloying and makes this material suited for applications in optoelectronics. Here, we report the crystalline structure and electrical ...

Raw data associated with the publication "Towards defect-free thin films of the earth-abundant absorber zinc phosphide by nanopatterning", first published in Nanoscale Advances on the 23nd November 2020. ...

Topological qubits based on Majorana Fermions have the potential to revolutionize the emerging field of quantum computing by making information processing significantly more robust to decoherence. Nanowires are a promising medium for hosting these kinds of ...
