The sensitivity of electron spin resonance has been improved up to the quantum limit through the use of a Josephson parametric microwave amplifier combined with high-quality-factor superconducting microresonators cooled at millikelvin temperatures.
Pulsed laser light locally melts nanostructured elements of a plasmonic metasurface to create coloured pixels with a resolution up to 127,000 dots per inch (DPI).
Air-stable monolayers of diamondoids can rival cesium's work-function-lowering ability and can dramatically increase field emission current through a radical cation mechanism.
A heat modulator designed to control the phase-coherent component of the thermal current at the nanoscale can be realized with a superconducting quantum interference device.
Effective magnetic fields as high as 30 T can arise in magnetically doped nanocrystals due to spin fluctuations alone, and can now be observed using ultrafast optical spectroscopy.
Cantilevers made of SrTiO3 grown on silicon use the flexoelectric effect to achieve electromechanical performances similar to piezoelectric bimorph cantilevers.
A violation of Bell's inequality, which is a direct proof of entanglement, can be observed in the solid state using the electron and nuclear spins of a single phosphorus atom in silicon.
Magnetic switching in spin–orbit-torque devices can be controlled by the geometry of the device, allowing different functionalities to be created from the same system.
Single-photon emission at room temperature can be achieved with hexagonal boron nitride due to electron and hole confinement in vacancy-related defects.
A molecular positioning device made from DNA origami can adjust the average distance between fluorescent molecules and reactive groups in steps as small as 0.04 nm.
Individual skyrmions in a PdFe atomic bilayer on Ir can be detected by all-electrical means using a non-spin-polarized scanning tunnelling microscope tip.
Isolated sub-2 nm nanopores in graphene exhibit diverse transport behaviours that are reminiscent of biological ion channels and arise from electrostatic and hydration interactions between ions and the pores.
A metal–insulator–metal architecture in which one metal is replaced by vertically aligned carbon nanotube antennae is used to convert light into direct current.
Angle-resolved photoemission measurements of electron-doped layers of tungsten diselenide reveal signatures of negative electronic compressibility that survive to much higher carrier densities than in conventional 2D electron gases.
The artificial evolution of the electrical properties of a disordered system of nanoparticles acting as single-electron transistors allows the realization of reconfigurable logic operations.
