Thin flakes of Cr₅Te₈, which exhibit a colossal anomalous Hall effect, can be synthesized using a phase-controlled chemical vapour deposition technique.

A van der Waals integration approach can be used to deposit single-crystal strontium titanate on two-dimensional molybdenum disulfide and tungsten diselenide, creating high-performance n- and p-doped field-effect transistors.

Quantum computing has attracted attention owing to its potential to solve problems that are intractable with traditional computing technologies; however, a scalable scheme for producing millions of qubits remains elusive. A new effort demonstrates a milestone to achieving this by fabricating qubits in the same factory where state-of-the-art semiconductor chips are manufactured.

This Review examines the development of perovskite light-emitting diodes, exploring the key challenges involved in creating efficient and stable devices.

By exploiting all three polarizations of a spin current in a ferromagnet/non-magnet/ferromagnet trilayer system, field-free spin–orbit torque switching is possible at low switching currents.

Few-nanometre-thick flakes of trigonal and monoclinic Cr₅Te₈ can be grown using chemical vapour deposition, with the monoclinic phase exhibiting an anomalous Hall conductivity of 650 Ω^–1 cm^–1 and anomalous Hall angle of 5%.

High-performance n-type molybdenum disulfide and p-type tungsten diselenide field-effect transistors can be fabricated using single-crystal strontium titanate dielectrics that are transferred onto two-dimensional semiconductors with the help of van der Waals forces.

High-quality van der Waals contacts between metals and two-dimensional semiconductors can be created using a selenium buffer layer that is deposited before the metal deposition process.

A palladium diselenide/molybdenum ditelluride van der Waals photovoltaic heterostructure can provide simultaneous broadband image sensing and convolutional processing.
