Ensuring a bright future for diamond electronics and sensors

November 5, 2024 sarah JonasResearch Results

To expand the potential use of diamond in semiconductor and quantum technologies, researchers are developing improved processes for growing the material at lower temperatures that won’t damage the silicon in computer chips. These advances include insights into creating protective hydrogen layers on quantum diamonds without damaging crucial properties like nitrogen-vacancy centers.

PPPL unveils new laboratory space to advance quantum information science

March 12, 2024 sarah JonasAnnouncement

On March 11, PPPL opened its new Quantum Diamond Lab, a space devoted to studying and refining the processes involved in using plasma, the electrically charged fourth state of matter, to create high-quality diamond material for quantum information science applications.

Technique could improve the sensitivity of quantum sensing devices

February 8, 2024 sarah JonasResearch Results

In quantum sensing, atomic-scale quantum systems are used to measure electromagnetic fields, as well as properties like rotation, acceleration, and distance, far more precisely than classical sensors can.

Superdeep diamonds provide a window on supercontinent growth

October 23, 2023 sarah JonasResearch Results

Diamonds contain evidence of the mantle rocks that helped buoy and grow the ancient supercontinent Gondwana from below, according to new research from a team of scientists led by Suzette Timmerman.

Experiments at the National Ignition Facility probe carbon at record pressures

January 27, 2021 sarah JonasResearch Results

Decades of studies have shown that carbon’s crystal structure has a significant impact on material properties. In addition to graphite and diamond, the most common carbon structures found at ambient pressures, scientists have predicted several new structures of carbon that could be found above 1,000 gigapascals (GPa). These pressures, approximately 2.5 times the pressure in Earth’s core, are relevant for modeling exoplanet interiors but have historically been impossible to achieve in the laboratory. That is, until now. Under the Discovery Science program, which allows academic scientists access to Lawrence Livermore National Laboratory’s (LLNL) flagship National Ignition Facility (NIF), an international team of researchers led by LLNL and the University of Oxford has successfully measured carbon at pressures reaching 2,000 GPa (5 times the pressure in Earth’s core), nearly doubling the maximum pressure at which a crystal structure has ever been directly probed.
