A scalable method to create ferroelectric FETs based on AlScN and 2D semiconductors
A key objective in the electronics engineering field is to develop transistors and other electronic components that are increasingly compact and efficient, utilizing readily available processes and materials. Among the transistors that have been found to be...
An optical method to polarize free electrons in a laboratory setting
Polarized electrons are electrons in which spins have a "preferred" orientation or are preferentially oriented in a specific direction. The realization of these electrons has notable implications for physics research, as it can pave the way toward the creation of...
A conductive self-healing hydrogel to create flexible sensors
The first experimental observation of subpicosecond electron bunches originating from an ultracold source
Identifying new sources that produce electrons faster could help to advance the many imaging techniques that rely on electrons. In a recent paper published in Physical Review Letters, a team of researchers at Eindhoven University of Technology demonstrated the...
The observation of a quantum disordered ground state in a triangular lattice magnet
Magnetic materials with a triangular lattice have been the focus of numerous research studies, as theoretical predictions suggest that they could exhibit spin liquid states. These are quantum phases of matter that present interesting characteristics, such as quantum...
Topologically structured light detects the position of nano-objects with atomic resolution
Optical imaging and metrology techniques are key tools for research rooted in biology, medicine and nanotechnology. While these techniques have recently become increasingly advanced, the resolutions they achieve are still significantly lower than those attained by...
Could dark photon dark matter be directly detected using radio telescopes?
Dark matter, matter in the universe that does not emit, absorb or reflect light, cannot be directly detected using conventional telescopes or other imaging technologies. Astrophysicists have thus been trying to identify alternative methods to detect dark matter for...
Team demonstrates quantum advantage on optimization problems with a 5,000-qubit programmable spin glass
Over the past decades, researchers and companies worldwide have been trying to develop increasingly advanced quantum computers. The key objective of their efforts is to create systems that will outperform classical computers on specific tasks, which is also known as...
A spontaneous topological Hall effect driven by a non-coplanar antiferromagnetic order in van der Waals materials
Ferromagnets are materials that become magnetized and remain so while they are exposed to an external magnetic field. In these materials, electric currents typically induce a so-called transverse Hall voltage (i.e., a voltage resulting from the deflection of...
