Abstract As a new type of microwave signal generator, spin-torque nano-oscillators (STNOs) based on skyrmions have potential application value. In recent years, hybrid with arbitrary helicity been proposed in chiral materials. this paper, we investigated the dynamics self-sustained oscillation magnetic nanodisks synthetic antiferromagnetic (SAF) multilayer structure, which can effectively eliminate Hall effect and ensure their stable circular motion. We found that smaller skyrmions, radius...

This work presents new insights into 3D logic circuit design with vertical junctionless nanowire FETs (VNWFET) accounting for underlying electrothermal phenomena. Aided by the understanding of nanoscale heat-transport in VNWFETs through multiphysics simulations, SPICE-compatible compact model captures temperature and trapping effects principally a shift device threshold voltage. Circuit level simulations indicate strong impact variation on functionality figures merits such as energy-delay...

Abstract Magnetic skyrmions are nanoscale spin textures with topological protection properties, which regarded as promising information carriers. When move along nanotracks, their trajectories will shift if affected by skyrmion Hall effect and pinning effect. In this work, the influence of trapezoidal notches in synthetic antiferromagnetic nanotracks on dynamics is investigated through micromagnetic simulation. The results exhibit that asymmetric energy barrier induced geometric structure...

Edge termination plays a crucial role in achieving near-ideal avalanche breakdown power semiconductor devices. In this paper, two edge designs, one GR (guard ring) [1], the other USAB-JTE (ultra-small-angle bevel junction extension) [2] that utilize planar ion implantation are developed and studied. The fabrication process only has single step does not need precise control over depth. Isolation is also done by same process, avoiding of etching possible etch-induced damages to Comprehensive...
