Disorder-driven symmetry suppression by van der Waals planar defects in a magnetic topological insulator
Rikkie Joris, Heyi Xia, Ana Beatriz Pedro Fontes +15
Magnetic topological insulators offer a platform to control electronic topology through magnetic order, yet reliable routes to tune their properties remain limited. Here, we show t…
Cryogenic piezoelectric effects in thin film strontium titanate devices
Ahmed Khalil, Anja Ulrich, Kamal Brahim +12
Next generation quantum technologies will need to rely on efficient transduction between electrical, optical, and mechanical quantum degrees of freedom to generate large-scale enta…
Stoichiometry and Thickness of Epitaxial SrTiO on Silicon (001): an Investigation of Physical, Optical and Electrical Properties
Andries Boelen, Marina Baryshnikova, Anja Ulrich +4
Strontium titanate (SrTiO, STO) stands out as a promising material for various electronic applications thanks to its exceptional dielectric properties. Molecular beam epitaxy…
Epitaxial growth of BaBiO3 thin films on SrTiO3(001) and MgO(001) substrates using molecular beam epitaxy and controlling their crystal orientations competition
Islam Ahmed, Stefan De Gendt, Clement Merckling
BaBiO3 has lately gained high research attention as a parent material for an interesting family of alloyed compositions with multiple technological applications. In order to grow a…
Structural transformation for BaBiO3-δ thin films grown on SrTiO3-buffered Si(001) induced by an in-situ Molecular Beam Epitaxy cooldown process
Islam Ahmed, Olivier Richard, Partrick Carolan +5
Oxygen loss is one of the common defect types in perovskite oxides whose formation can be caused by a low oxygen background pressure during growth or by straining the thin film. Cr…
Engineering high Pockels coefficients in thin-film strontium titanate for cryogenic quantum electro-optic applications
Anja Ulrich, Kamal Brahim, Andries Boelen +13
Materials which exhibit the Pockels effect are notable for their strong electro-optic interaction and rapid response times and are therefore used extensively in classical electro-o…
