In the fall of 2024, DFM successfully installed a state-of-the-art, custom-built Molecular Beam Epitaxy (MBE) system, led by Sabbir A. Khan, Head of the Quantum Materials Team, to advance our quantum materials research. Following installation and commissioning, the system is now fully operational, and we have already begun producing high-quality quantum materials.
The new MBE cluster comprises three specialized ultra-high vacuum chambers, each designed to fabricate exceptionally pure materials for next-generation quantum devices:
- III-V MBE Chamber: Dedicated to the growth of high-quality photonic qubits.
- Superconductor MBE Chamber: Enables the fabrication of superconducting qubits.
- Preparation & Cleaning Chamber: Ensures sample purity for ultra-high vacuum processes.
Each chamber is equipped with in-situ metrology and direct in-situ lithography, enabling precise material engineering at the nanoscale.
By the end of 2025, DFM will further expand the facility with an additional customized chambers optimized for high-purity Si & Ge materials, paving the way for electron/hole spin qubits and advanced quantum photonic devices. This comprehensive platform positions DFM as a national hub for cutting-edge quantum material fabrication, driving innovation in quantum computing, communication, and sensing.
The project is supported by Innovation Fund Denmark (IFD), European Metrology Funds, and by funds from Danish Agency for Higher Education and Science.
DFM is Denmark’s National Metrology Institute and one of the seven Approved Technological Service (GTS) institutes in the country.
