Chirality, a basic property of symmetry breaking, is crucial for fields such as biology and physics. Recent advances in the study chiral systems have stimulated interest discovery symmetry-breaking states that enable exotic phenomena spontaneous gyrotropic order superconductivity. Here we examine interaction between light chirality electron spins indium selenide effect magnetic field on emerging tunnelling photocurrents at Van Hove singularity. Although symmetric under linearly polarized...
In this work, we investigate the fundamental effects contributing to energy storage enhancement in on-chip ferroelectric electrostatic supercapacitors with doped high-k dielectrics. By optimizing density and efficiency nanometer-thin stacks of Si:HfO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> Al O <sup xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> , achieve 90 J/cm efficiencies up 90%. We demonstrate for first time that such...
In this work we propose and demonstrate the integration of ferromagnetic nanosized cobalt barrier gates in quantum dots arrays on ultra-thin fully-depleted Silicon-On-Insulator (SOI) nanowires. This innovative structure enhances both driving addressability, while minimizing decoherence fields for electron spin qubits. Charge noise spectra show sub-$1\cdot 10^{-6}\mathrm{e}^{2}$fflz values at 1 Hz, demonstrating a low impact from Cogates. Our double dot experimental data stable confinement 10...
