Skyrmions for Advanced Magnetic Memory and Logic: Device Modeling KU Leuven
The current thesis focuses on studying magnetic configurations called skyrmions. These can be regarded as configurations of spins that are topologically protected and have a chiral, whirling configuration. Their small size and robustness to defects, qualifies them as potential candidates for next-generation spintronic devices. Such devices can implement memory and/or logic functions. The aim of the PhD is to study the skyrmion structures and ...
Energy filtering in silicon nanowires and nanosheets using a geometric superlattice and its use for steep-slope transistors KU Leuven Universiteit Antwerpen
© 2018 Author(s). This paper investigates energy filtering in silicon nanowires and nanosheets by resonant electron tunneling through a geometric superlattice. A geometric superlattice is any kind of periodic geometric feature along the transport direction of the nanowire or nanosheet. Multivalley quantum-transport simulations are used to demonstrate the manifestation of minibands and minibandgaps in the transmission spectra of such a ...
Anisotropic bulk and planar Heisenberg ferromagnets in uniform, arbitrarily oriented magnetic fields KU Leuven Universiteit Antwerpen
Today, further downscaling of mobile electronic devices poses serious problems, such as energy consumption and local heat dissipation. In this context, spin wave majority gates made of very thin ferromagnetic films may offer a viable alternative. However, similar downscaling of magnetic thin films eventually enforces the latter to operate as quasi-2D magnets, the magnetic properties of which are not yet fully understood, especially those related ...
Spin-based majority computation KU Leuven
© Springer International Publishing AG, part of Springer Nature 2019. The downscaling of Complementary Metal Oxide Semiconductor (CMOS) devices will come to an end in the following decade. This has accelerated research that explores new device concepts that can help the semiconductor industry move forward, beyond the CMOS roadmap. Such device concepts include spin-based technologies which have a propensity to low-energy operation and ...
Skyrmion electrical detection with the use of three-dimensional topological insulator / ferromagnetic bilayers KU Leuven Universiteit Antwerpen
The effect of the magnetic skyrmion texture on the electronic transport properties of the TI surface state coupled to a thin-film FM is numerically investigated. It is shown that both Bloch (vortex) and Néel (hedgehog) skyrmion textures induce additional scattering on top of a homogeneous background FM texture which can modify the conductance of the system. The change in conductance depends on several factors including the skyrmion size, the ...
