Wide bandgap semiconductors

We are strengthening our role in the development of solid-state quantum systems, such as optical active spin quantum bits, quantum memories and registers.

These are basic elements required for various applications in quantum technologies, e.g. long-distance quantum communications, quantum sensing and quantum computing. Our expertise extends from materials science, which includes design and growth of quantum-grade materials (SiC, III-nitrides and other semiconductors) and structures for nanophotonic and other quantum devices, to characterization, control and manipulation of optical spin qubits.

We also develop MOCVD of group III nitrides, particularly ultra-wide bandgap AlN, and resolve doping issues. We further develop group III nitrides at the 2D limit by leading predictive theoretical modeling and MOCVD approaches and explore new material performance for electronics at nanoscale.
