Unveiling ultra-thin electron liquids in silicon
Soft X-rays enable scientists to visualise non-invasively the electronic properties of ultra-thin dopant layers buried within semiconductor wafers.
A better understanding of water
Potentiometric map of water molecules created
Semiconductors reach the quantum world
Boosted with superconductivity: Semiconductor technology can get a new twist by exploiting quantum effects in superconductors.
Understanding the physics in new metals
Together with international colleagues, PSI researchers have now been able to make correlated metals more readily usable for applications in superconductivity, data processing, and quantum computers.
Customising an electronic material
PSI scientists have investigated a material that could be suitable for future data storage applications. They have manipulated the crystalline structure of their sample while measuring how this affects the material’s magnetic and electronic properties.
Weyl fermions discovered in another class of materials
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.
New material also reveals new quasiparticles
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.
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.
HERCULES school 2019 at SLS
In the week of April 1-5 PSI welcomes 20 PhD students and postdocs taking part in the European HERCULES 2019 school on Neutron and Synchrotron Radiation. They will attend lectures and perform two days of practical courses at several beam lines of the Swiss Light Source.
