Topological spin-texture transitions in van der Waals magnets revealed by X-ray Fourier transform holography
Sourav Chowdhury, Soumyaranjan Dash, Michael Schneider +14
Nontrivial topological spin-textures, such as skyrmions, merons, bimerons, and skyrmioniums, are envisioned as robust building blocks for future memory and logic devices. Controlla…
Active Noise Reduction in Si/SiGe Gated Quantum Dots
Rajat Bharadwaj, Parvathy Gireesan, Harikrishnan Sundaresan +5
Solid-state quantum technologies such as quantum dot qubits and quantum electrical metrology circuits rely on quantum phenomena at ultra-low energies, making them highly sensitive…
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…
Resistively detected electron spin resonance and g-factor in few-layer exfoliated MoS2 devices
Chithra H. Sharma, Appanna Parvangada, Lars Tiemann +3
MoS2 has recently emerged as a promising material for enabling quantum devices and spintronic applications. In this context, an improved physical understanding of the g-factor of M…
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…
