By controlling two voltage gates separately from one another, a spatial light modulator has been made that can continuously vary the phase of 360 degrees while independently adjusting the amplitude.
Function implementation and optimization in nanoscale and quantum-electronic devices become increasingly challenging with the growing complexity of the devices. Training a deep neural network with the physical device response and searching for the functionality in the digital device can ease this challenge.
Foliar application of different forms of nanoscale copper to plant seedlings induces material-specific biochemical and molecular changes in root tissue that stimulate plant defence against soybean sudden death syndrome.
Epitaxial quantum dot charge spin qubits offer efficient quantum light links, but their coherence is limited by interactions with the nanoscale ensemble of atomic nuclear spins. Employing nuclear spins instead as its hardware, strain-free GaAs/AlGaAs quantum dots can constitute a fully functional two-qubit quantum register.
Holography of incoherent emission from SERS probes allows multiplexed single-particle localization in three dimensions in one shot using a wide-field microscope.
Two-dimensional conjugated metal–organic frameworks used as an electron-extraction layer enable the realization of highly stable perovskite solar cells with minimized lead ion leakage.
A complex-amplitude metasurface hologram is conceptually designed and three-dimensionally printed. The device allows for high-bandwidth orbital angular momentum multiplexing holography and holographic video displays.
Planar metasurfaces are a valuable tool to achieve custom-tailored photoluminescence from quantum emitters. The incorporation of a WSe2 monolayer into a photonic crystal slab with geometric phase defects enables spin-dependent manipulation of the emission from valley excitons of the WSe2, as well as from randomly placed quantum emitters.
Metallic glasses possess intriguing functional properties, but controlled fabrication with nanoscale feature sizes remains challenging. Thermal co-drawing within a viscosity-matched polymer matrix enables the fabrication of uniform metallic glass fibres with feature sizes down to a few tens of nanometres, arbitrary transverse geometries and aspect ratios greater than 1010.
Well-controlled multilayer graphene up to four layers thick with a defined stacking sequence is synthesized via SiC alloy formation on a Cu(111) substrate.
Gene brushes patterned as synthetic operons on two-dimensional silicon compartments with defined geometry allow the investigation and regulation of nanoscale multi-protein assemblies.
A combination of room-temperature nano-optical imaging and spectroscopy and atomistic theory reveals highly localized exciton states in nanobubbles of localized strain in monolayer WSe2.
The realization of high-quality van der Waals contacts on monocrystalline halide perovskite thin films enables the probing of their long-range carrier and photocarrier transport properties.
