Grant to nano-research from the Carl Trygger foundation
A research team led by professor Carlo Canali at Linnaeus University is granted SEK 822,000 by the Carl Trygger Foundation to theoretically and experimentally investigate nano-wires and -structures. The grant comprises a postdoc post, operation and equipment.
The project that has been granted is called Nanospintronics with magnetic topological core-shell nanowires and will be carried out in 2021–2023. The purpose of the project is to theoretically and experimentally investigate quasi one-dimensional (1D) nanowires (NWs) and core-shell NW heterostructures made of different classes of topological quantum matter, such as topological insulators, topological crystalline insulators and Weyl and Dirac topological semimetals.
The elucidation of the magnetic topological phases emerging in these quasi 1D systems when surrounded by magnetic shells, and the associated novel spin-transport phenomena, are the main themes of the project. The researchers will focus on the fundamental electronic, magnetic and transport properties of these NW systems, which can lead to applications in topological nanospintronics.
The theoretical and computational work is led by Carlo Canali, professor and head of the research group Condensed Matter Physics at Linnaeus University. The work will be carried out in close collaboration with three experimental teams:
- Linnaeus University and the Institute of Physics of the Polish Academy of Science, led by Janusz Sadowski
- Chalmers University of Technology, led by Saroj Prasad Dash
- Max Planck Institute of Microstructure Physics at Halle, led by Paolo Sessi
Carl Trygger's foundation for scientific research has the task of providing research support for natural sciences in the broadest sense, and the technical applications of these sciences, and with a focus that can be expected to contribute to the development of business and industry in Sweden. The project has received a grant of SEK 822,000 and includes a postdoctoral fellow as well as operation and equipment.
