Aligning magic-angle twisted bilayer graphene to boron nitride layers introduces a gate hysteresis coexisting with its strongly correlated phases. This bistability enables electrical switching between superconducting, metallic and insulating states.
Topological magnetic monopoles are non-local spin textures that are robust to thermal and quantum fluctuations, but they are difficult to study at the nanoscale in real space. Now, soft X-ray vector ptycho-tomography is demonstrated to determine the three-dimensional magnetization vector and emergent magnetic field of such magnetic monopoles in a ferromagnetic meta-lattice.
Electrons in two-dimensional semiconductor moiré materials experience competing magnetic interactions. Magneto-optical measurements of moiré devices with controlled screening of the Coulomb interactions now evidence a Wigner–Mott insulating state with frustrated magnetic interactions.
The interaction between distinct excitations in solids is of both fundamental interest and technological importance. The layered magnetic semiconductor CrSBr exhibits strong coupling between excitons and coherently hybridized magnons, where both magnetic fields and strain can tune the coupling precisely.
A single DNA or RNA duplex can rotate unidirectionally when subject to an external electric field, generating sufficient torque to power rotary motion of larger nanoscale objects.
Femtosecond electron diffraction and ab initio theory unravel ultrafast lattice dynamics in photoexcited two-dimensional heterostructures during charge transfer.
Although the toxicity of graphene‐based nanomaterials on human health has been extensively studied, their impact on the microbiome remains poorly understood. Using zebrafish as a model, we show that graphene oxide modulates the immune system in a microbiome‐dependent manner through a mechanism mediated by the aryl hydrocarbon receptor. The study suggests an interplay among graphene‐based nanomaterials, microbiome and innate immune system.
The authors identified the origin of LiH formation and a new method of LiF formation on a lithium metal anode, which is through the anion decomposition on the cathode side followed by crosstalk.
Engineering of the interfacial properties between a semiconducting thin film and a stretchable substrate using tough interfacial bonding enables a notable delay in microcrack formation.
Magnetic textures at the nanoscale are usually hard to resolve. This high-resolution electron microscopy method enables the imaging of the internal structure of magnetic textures with higher resolution and precision than the optical limit of the instrument.
Low-noise amplification of feeble microwave signals is essential for superconducting quantum circuitry. Now, a gate-tunable Josephson parametric amplifier made from graphene shows 24 dB amplification paired with 10 MHz bandwidth and –130 dBm saturation power.
Raman scattering within plasmonic waveguides is found to be directed into a single mode with near-unity efficiency, offering a route to broadband SERS enhancements over extended sensing volumes.
Parametric amplifiers enable the low noise readout of systems with intrinsically low energy scales. Now, a parametric amplifier leveraging a graphene Josephson junction exhibits a gate-tunable working frequency and a gain exceeding 20 dB with added noise close to the standard quantum limit.
Twisting bilayer graphene to specific angles can yield correlated phases. A superconducting quantum interference device made from this magic-angle twisted bilayer graphene makes it possible to control the phase drop across a Josephson junction in this material.
The technology commonly used for sewer pipe repairs emits airborne nanoplastic particles at a scale that may impact the environment and air quality in urban areas.
The valley pseudospin of electrons may serve as an additional degree of freedom for future on-chip low-energy signal processing. Now, a nanophotonic circuit that integrates a monolayer of WS2 routes valley indices unidirectionally via the chirality of the photons.
