Objectives

 Fabrication of novel three-dimensional architectures

The goal is to fabricate three-dimensional nanoarchitectures with large curvature. According to the theoretical prediction (WP2), the radius of curvature in the order of 10 nm has to be achieved to observe sizable curvature effects on the spin-orbit coupling (SOC). The onset of the SOC in curved nanomembranes will be characterized using transport measurements carried out in a nonlocal spin valve configuration (WP3).

Superconductivity and spin-orbit coupling in curved systems

A proper understanding of quantum physics on curved surfaces embedded in the ordinary three-dimensional space has become immediate due to the present drive in constructing low-dimensional nanostructures such as sheets and tubes that can be bent into curved, deformable objects such as tori and spirals.

 Spin-transport in three-dimensional nanoarchitectures

Curvature-induced effects in nanomembranes will open a new perspective for the technological development of spintronic devices. Spintronics is a vibrant scientific field that has led to technological applications like the magnetic sensors present in modern hard disk drives - its potential impact for future information technologies clearly stands out.

Topological superconductivity in curved nanoarchitectures

The goal of this WP is to shed a light on ways to geometrically tune the physical ingredients for the generation of Majorana modes in order to finally achieve their experimental detection. As a first step, the effects of geometric curvature on the superconducting order parameter pairing symmetry will be investigated.
