Periodic polar vortices in BaTiO3/SrTiO3 superlattices monolithically grown on silicon
Abstract Polar textures in ferroelectric superlattices have been so far reported almost exclusively in PbTiO 3 -based systems and predominantly on oxide substrates. Owing to their nanometer-scale dimensions and emergent functionalities, whirling topological polar textures would b...

ABSTRACT In this work, we investigate the diffusion‐controlled growth mechanism and kinetics of gallium arsenide (GaAs) islands on CMOS‐compatible Si(001) nanotip wafers using nanoheteroepitaxy by gas‐source molecular beam epitaxy. Si nanotips embedded in a silicon dioxide (SiO 2...
