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.
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.
Interaction- and defect-free van der Waals contacts between metals and two-dimensional semiconductors
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.
