Tunnel-rate controlled local heat distribution in mesoscopic circuits
Parvathy Gireesan, Umang Soni, Harikrishnan Sundaresan +2
Solid-state quantum technologies, including qubits and quantum metrology circuits, demand milli-Kelvin operation to preserve fragile quantum states from classical noise. While the…

Density-driven scattering and valley splitting in undoped Si/SiGe two-dimensional electron system
Lucky Donald Lyngdoh Kynshi, Umang Soni, Chithra H Sharma +7
Undoped Si-SiGe two-dimensional electron gas (2DEG) provide an ideal platform for hosting quantum-dot spin-qubits owing enhanced spin dephasing times and compatibility with standar…

Refining Au/Sb alloyed ohmic contacts in undoped Si/SiGe strained quantum wells
LuckyDonald L Kynshi, Umang Soni, Chithra H Sharma +2
Shallow undoped Si/SiGe quantum wells are the leading platforms for hosting quantum processors based on spin-qubits. The ohmic contacts to the electron gas in these systems are acc…
