Gate-tunable magnetic damping in van der Waals Heterostructures
Lukas Cvitkovich, Klaus Zollner, Jaroslav Fabian
Active control of magnetic damping is a crucial capability for the development of low-power, tunable spintronic devices. In this work, we demonstrate that the intrinsic magnetic da…
Resonant magnetic proximity hot spots in Co/hBN/graphene
Klaus Zollner, Lukas Cvitkovich, Riccardo Silvioli +2
Magnetic proximity effects in Co/hBN/graphene heterostructures are systematically analyzed via first-principles calculations, demonstrating a pronounced localized spatial variation…
Valley Splittings in Si/SiGe Heterostructures from First Principles
Lukas Cvitkovich, Tancredi Salamone, Christoph Wilhelmer +3
We compute valley splittings in Si/SiGe superlattices using ab initio density functional theory (DFT). This first-principle approach is expected to provide an excellent description…
Valley physics in the two bands model for SiGe heterostructures and spin qubits
Tancredi Salamone, Biel Martinez Diaz, Jing Li +2
We discuss the choice and implementation of inter-valley potentials in the so-called two bands model for the opposite , or valleys of silicon…
Machine Learning Prediction of Magnetic Proximity Effect in van der Waals Heterostructures: From Atoms to Moiré
Lukas Cvitkovich, Klaus Zollner, Jaroslav Fabian
We introduce a machine learning framework that efficiently predicts large-scale proximity-induced magnetism in van der Waals heterostructures, overcoming the high computational cos…
Spin injection and detection in all-van der Waals 2D devices
Jan Bärenfänger, Klaus Zollner, Lukas Cvitkovich +7
In this work we report efficient out-of-plane spin injection and detection in an all-van der Waals based heterostructure using only exfoliated 2D materials. We demonstrate spin inj…
Machine Learning Force Field for Thermal Oxidation of Silicon
Lukas Cvitkovich, Franz Fehringer, Christoph Wilhelmer +3
Looking back at seven decades of highly extensive application in the semiconductor industry, silicon and its native oxide SiO are still at the heart of several technological de…
Coherence limit due to hyperfine interaction with nuclei in the barrier material of Si spin qubits
Lukas Cvitkovich, Peter Stano, Christoph Wilhelmer +4
On the quest to understand and reduce environmental noise in Si spin qubits, hyperfine interactions between electron and nuclear spins impose a major challenge. Silicon is a promis…
Modeling the Initial Stages of Si(100) Thermal Oxidation: An Ab-initio Approach
Lukas Cvitkovich, Dominic Waldhör, Al-Moatassem El-Sayed +3
Silicon together with its native oxide SiO was recognized as an outstanding material system for the semiconductor industry in the 1950s. In state-of-the-art device technology,…
