Mihai Gabureac joined our group in August 2017. He is an expert in cleanroom micro- and nano-fabrication with experience in thin film vacuum deposition, selective etching, Ar milling, photo- and e-beam-lithography, as well as advanced surface and structural characterization and metrology. He has worked previously with hybrid magnetic-superconducting tunnel junctions and has developed processes for the oxidation/growth of Alox and MgO tunnel junction barriers using feedback from magnetic devices. As a technical staff member of the Engineering Unit of ETH Quantum Centre (formally known as Quantum Engineering Centre), Mihai was in charge of the optimization and development of new cleanroom fabrication processes and materials for the fabrication of quantum devices, such as Josephson tunnel junctions and superconducting microwave resonators. He also offered microfabrication expertise and provided high quality superconducting Nb and NbTiN coatings for a large network of QSIT collaborators, based on his cleanroom expertise, and quantum circuits knowledge acquired in the Qudev lab. He has worked both in FIRST and BRNC ETH cleanrooms and has supervised all the fabrication and PVD activities. As a mentor and equipment responsible in the FIRST cleanroom, he also provided regular user trainings, micro-fabrication advice and maintenance services. After leaving the Quantum Device Lab he joined the group of Prof. Werner Wegscheider.
