A clean contact

With the help of a metal deposition process that uses a selenium buffer layer, van der Waals contacts that are interaction- and defect-free can be formed between metals and two-dimensional semiconductors. The computer-generated image on the cover highlights the probing of p-type tungsten diselenide (WSe2) field-effect transistors with gold van der Waals contacts, which can be created with the technique.

  • 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.
