Strain-control over the valley degree of freedom
16.05.2024
Department of the Ecole Normale Supérieure Paris, France in collaboration with scientists from URANOS SOLARIS Centre have published in Physical Review Letters the results of their research on the Valley-Polarized Quantum Hall Phase Dirac System. The different local band minima – called valleys – of a multivalley 2D topological insulator have been independently characterized using ARPES experiments. An efficient control over their electronic population using mechanical strain has been demonstrated.

Effect of Ne+ 250 keV ion implantation on the critical parameters of composite 2G HTS tapes
03.04.2024
A Polish team of researchers led by Dr. Paweł Pęczkowski from the Institute of Physical Sciences, Faculty of Mathematics and Natural Sciences, Cardinal Stefan Wyszyński University used the PIRX beam to study the properties of the electronic structure of 2G HTS tapes (second generation high-temperature superconducting tapes) previously subjected to the process of implantation with Ne+ noble gas ions with an energy of 250 keV. The results of the investigation were published in the journal Applied Surface Science published by Elsevier.

The special role of magnetic Ni ions in the electronic structure
19.03.2024
An international research team led by researchers from the Institute of Physics (Zagreb, Croatia) revealed the electronic structure of nickel intercalated 2H-NbS2. The combination of theoretical and experimental approaches provided insight into the peculiar role of the intercalated Ni ions in the electronic structure of the layered compound. The work received “Editors’ Suggestion” from Physical Review B.

Hercynite – the mysterious refractory spinel compound understood!
21.02.2024
The reaserch team from AGH University in Kraków used beamline PIRX to study the sructural properties of spinel compounds, including hercynite, FeAl2O4, which belongs to wide & mixabe oxide spinel group with dense packing and cubic AB2 O4 structure. This work was conducted in a team led by PhD Eng. Ilona Jastrzębska from the Faculty of Materials Science and Ceramics.
