Effects of Integrated Heatsinking on Superconductivity in Tantalum Nitride Nanowires at the 300 Millimeter Scale
Ekta Bhatia, Tharanga R. Nanayakkara, Chenyu Zhou +14
We report the superconducting properties of tantalum nitride (TaN) nanowires and TaN/copper (TaN/Cu) bilayer nanowires fabricated on 300 mm silicon wafers using CMOS-compatible pro…
Ta-based Josephson junctions using insulating ALD TaN tunnel barriers
Ekta Bhatia, Jack Lombardi, Tuan Vo +16
Josephson junctions form the core circuit element in superconducting quantum computing circuits, single flux quantum digital logic circuits, and sensing devices such as SQUIDs. Alu…
Engineering of Niobium Surfaces Through Accelerated Neutral Atom Beam Technology For Quantum Applications
Soumen Kar, Conan Weiland, Chenyu Zhou +16
A major roadblock to scalable quantum computing is phase decoherence and energy relaxation caused by qubits interacting with defect-related two-level systems (TLS). Native oxides p…
Chemical Mechanical Planarization for Ta-based Superconducting Quantum Devices
Ekta Bhatia, Soumen Kar, Jakub Nalaskowski +9
We report on the development of a chemical mechanical planarization (CMP) process for thick damascene Ta structures with pattern feature sizes down to 100 nm. This CMP process is t…
