In January 2019 it began regular operation. Henrik Lemke, head of the SwissFEL Bernina research group, gives an interim report. 12 July 2019 Weyl fermions discovered in another class of materials Media Releases Matter and Material Materials Research Research Using Synchrotron Light A particular variety of particles, the so-called Weyl fermions, had previously only been detected in certain non-magnetic materials. But now researchers at PSI have experimentally proved their existence for the first time in a specific paramagnetic material. 25 June 2019 PSI School for Master Degree Students - Introducing Photons, Neutrons and Muons for Condensed Matter Physics and Materials Science From 17 – 21 June 2019 the Neutron and Muon Division (NUM) and the Photon Science Division (PSD) of PSI hosted 18 Master Degree students of physics, chemistry, materials and interdisciplinary science, as well as nuclear engineering to provide an introduction to the characterization of materials with large scale facilities like SINQ, SμS, SLS and SwissFEL. The course taught a basic understanding of how photons, neutrons and muons interact with matter, and how this knowledge can be used to solve specific problems in materials research. Details of the program can be found at http://indico.psi.ch/event/PSImasterschool 7 May 2019 New material also reveals new quasiparticles Media Releases Matter and Material Materials Research Research Using Synchrotron Light Researchers at PSI have investigated a novel crystalline material at the Swiss Light Source SLS that exhibits electronic properties never seen before. Among other things, they were able to detect a new type of quasiparticle: so-called Rarita-Schwinger fermions. 3 May 2019 An iodine polymeric chain with tunable conductivity The progressive hydrostatic compression of I2 and I3- units in an organic salt lead to a homoatomic polymeric chain. As the I---I distance collapses the covalent character of the interaction becomes more relevant, leading to a pressure-tunable increased conductivity. 3 May 2019 New study gives compelling evidence that tungsten diphosphide is a type-II Weyl semimetal Researchers at NCCR MARVEL have combined first principles calculations with soft X-ray angle-resolved photoemission spectroscopy to examine tungsten diphosphide’s electronic structure, characterizing its Weyl nodes for the very first time. In agreement with density functional theory calculations, the results revealed two pairs of Weyl nodes lying at different binding energies. The observation of the Weyl nodes, as well as the tilted cone-like dispersions in the vicinity of the nodal points, provides compelling evidence that the material is a robust type-II Weyl semimetal with broken Lorentz invariance. This is as MARVEL researchers predicted two years ago. The research has been published in Physical Review Letters as an Editor's Suggestion. 12 April 2019 Prof. Helena Van Swygenhoven presented the plenary Kavli lecture at the MRS spring meeting 2019 Plenary Session Featuring The Fred Kavli Distinguished Lectureship in Materials Science: Tuesday, April 23 8:15 am – 9:30 am PCC North, 100 Level, Ballroom 120 D 12 April 2019 Carlos Vaz Selected by the Journal of Materials Chemistry C as Outstanding Reviewer in 2018 SIM beamline scientist Carlos Vaz was recognized as outstanding referee for providing high quality peer review for the Journal of Materials Chemistry C (Royal Society of Chemistry). 8 April 2019 X‐Ray Writing of Metallic Conductivity and Oxygen Vacancies at Silicon/SrTiO3 Interfaces Lithography‐like writing of conducting regions at the interface between SrTiO3 and amorphous Si using X‐ray irradiation opens ways for spatially controlled functionalities in oxide heterostructures. 1 2 3 4 5 6 7 8 9 Next page ›› Last page Last » Sidebar More Scientific Highlights PSI Highlights
