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.
Clathrin, a three-legged protein complex, can form regular two-dimensional lattices on a variety of substrates. These lattices can be functionalized with nanoparticles or enzymes for sensing applications.
Thin-film transistors made from solution-processed single-walled carbon nanotubes are used to fabricate large-scale integrated arrays of complementary static random access memory cells.
Silicon pillars with elliptical cross-section are used to fabricate efficient metasurfaces that allow simultaneous control of the phase and polarization of the transmitted electromagnetic radiation.
The scanning tunnelling microscope can be used to image and manipulate individual defects in bulk insulating hexagonal boron nitride by capping the material with a monolayer of graphene.
The generation of strain in SnTe thin films due to lattice mismatch with the PbSe substrate can be used to tune the position of Dirac nodes in momentum space.
Atomically thin gratings, fabricated in single-layer graphene, can act as nanomechanical diffraction elements for high-contrast quantum interference of phthalocyanine molecules.
Capacitively coupled quantum dots can be used to realize a thermoelectric device that decouples the direction of flow of the electrical current from that of the heat current.
Gas transport through discrete ångström-sized pores in monolayer graphene can be controlled using gold clusters formed on the surface of the graphene, which can migrate and partially block a pore.
High-frequency impedance spectroscopy using CMOS nanocapacitor arrays allows microparticles and living cells to be imaged in real time under physiological salt conditions.
Different adjacent molecules adsorbed on a surface can be distinguished by their Raman modes using a plasmon-enhanced Raman scattering technique with a spatial resolution below 1 nm.
The direction of a single photon emitted from a quantum emitter, and its coupling to a photon waveguide, can be controlled by the helicity of the optical transition.
A design approach for engineering wireframe DNA nanostructures, in which each vertex and line segment can be individually controlled, can be used to fabricate complex structures including quasicrystalline two-dimensional patterns and reconfigurable three-dimensional Archimedean solids.
