Dense atomic-scale 2D/2D Schottky heterojunctions are achieved in the graphene-based superlattice nanocomposites by controlled deintercalation, largely facilitating spatial charge separation that optimizes their microwave-absorbing performance.

Understanding and controlling the quantum friction remain challenging. Here, the authors reveal pseudo-Landau levels splitting induced quantum friction at solid-solid interfaces via engineering the nanocurvature geometry of folded graphene edges.

Ultrafast electron sources are essential for time-resolved electron microscopy techniques, but they usually suffer from limited stability and short lifetimes. Here, the authors report the fabrication of ultrafast hot-electron sources consisting of graphene films integrated on a single-mode optical fibre, showing enhanced stability and longevity.

The coupling of ferroelectricity and magnetic order enables the tunability of material properties. Here, authors realize magnetic-field-enhanced ferroelectricity and electrical-field-controlled magneto-transport in non-magnetic moiré superlattices.

Precise control of charge and spin states in quantum dots is often challenging. Here, the authors show systematic manipulation of the electron occupation in graphene nanoribbons laying on MgO.

Freestanding membranes of hafnium zirconium oxide can be created using pulsed laser deposition method and used as the top-gate dielectric in molybdenum disulfide transistors.

The transfer of 2D materials from growth to device substrates has hampered their scalability. Now, a robotic, solvent-free process promises clean, high-yield and wafer-scale integration.

Fractionalized excitations typically require ultra-clean materials at low temperature and high magnetic field to emerge. Experiments on a simple graphene platform now reveal ideal conditions for the visualization of these fragile collective states.

Graphene plasmon polaritons are expected to enable rapid data transfer and processing; however, these plasmons are difficult to access. Terahertz electronics now facilitate the efficient generation, manipulation and on-chip detection of wave packets lasting as little as 1.2 ps. This advance could lead to the development of nanoscale terahertz circuits.

Rhombohedral graphene is an emerging material with a rich correlated-electron phenomenology, including superconductivity. The magnetism of symmetry-broken trilayer graphene has now been explored, revealing important details of the physics and providing a roadmap for broader explorations of rhombohedral graphene.

Wavefunctions in graphene artificial atoms reveal giant orbital magnetic moments.
