[Bibtex]@article{Asa2021, abstract = {Interfaces play a crucial role in the study of novel phenomena emerging at heterostructures comprising metals and functional oxides. In this work, we consider Cr/BaTiO3 heterostructures grown on Nb:SrTiO3 (0 0 1) substrates. Chromium thin films with 2 nm nominal thickness are deposited by molecular beam epitaxy on the BaTiO3 layer, and subsequently annealed in vacuum at temperatures ranging from 800 K to 970 K, and finally exposed to 10−7 torr of molecular oxygen for 300 s. Highly ordered films are obtained for each of this condition, ranging from metallic Cr to insulating Cr2O3 with tetragonal structure. Quite unexpectedly, an intermediate – fully ordered – case exists, with the co-presence of Cr and Cr2O3 compounds, each one with its proper crystal orientation. These results show the opportunity of controlling the metal/oxide state of crystalline Cr films grown onto the ferroelectric template BaTiO3/Nb:SrTiO3. {\textcopyright} 2020 Elsevier B.V.}, address = {Dipartimento di Fisica, Politecnico di Milano, c/o Polifab, Via G.

Recently, a route has been demonstrated for forming conducting heterostructure membranes of LaAlO3 and SrTiO3, the canonical system for oxide electronics. In this route, the epitaxial growth of LaAlO3 on SrTiO3 resulted in a strained state that relaxed by producing freestanding membranes with random sizes and locations. Here, we extend the method to enable self-formed LaAlO3/SrTiO3 micromembranes with control over membrane position, their lateral sizes from 2 to 20 $\mu$m, and with controlled transfer to other substrates of choice. This method opens up the possibility to study and use the two-dimensional electron gas in LaAlO3/SrTiO3 membranes for advanced device concepts.}, annote = {doi: 10.1021/acsami.0c21612}, author = {Dahm, Rasmus T and Erlandsen, Ricci and Trier, Felix and Sambri, Alessia and Gennaro, Emiliano Di and Guarino, Anita and Stampfer, Lukas and Christensen, Dennis V and Granozio, Fabio Miletto and Jespersen, Thomas S}, doi = {10.1021/acsami.0c21612}, issn = {1944-8244}, journal = {ACS Applied Materials & Interfaces}, month = {mar}, number = {10}, pages = {12341--12346}, publisher = {American Chemical Society}, title = {{Size-Controlled Spalling of LaAlO3/SrTiO3 Micromembranes}}, url = {https://doi.org/10.1021/acsami.0c21612}, volume = {13}, year = {2021} }

[Bibtex]@article{Longo2020a, abstract = {When coupled with ferromagnetic layers (FM), topological insulators (TI) are expected to boost the charge-to-spin conversion efficiency across the FM/TI interface. In this context, a thorough control and optimization of the FM/TI interface quality are requested. Here, the evolution of the chemical, structural, and magnetic properties of the Fe/Sb2Te3 heterostructure is presented as a function of a rapid mild thermal annealing conducted on the Sb2Te3-TI (up to 200 °C). While the bilayer is not subjected to any thermal treatment upon Fe deposition, the annealing of Sb2Te3 markedly improves its crystalline quality, leading to an increase in the fraction of ferromagnetic Fe atoms at the buried Fe/Sb2Te3 interface and a slight lowering of the magnetic coercivity of the Fe layer. The method is an efficient tool to clean up the Fe/Sb2Te3 interface, which may be extended to different FM/TI heterostructures. Simultaneously to the interface reconstruction, a constant ≈20% fraction of FeTe develops at the interface. Since FeTe can display superconductivity, the Fe/Sb2Te3 system could have potentialities for exploiting phenomena at the edge of magnetism, superconductivity and topology. {\textcopyright} 2020 Wiley-VCH GmbH}, address = {CNR-IMM, Unit of Agrate Brianza, Via C.

[Bibtex]@article{Sambri2020, abstract = {Abstract The discovery of 2D conductivity at the LaAlO3/SrTiO3 interface has been linking, for over a decade, two of the major current research fields in materials science: correlated transition-metal-oxide systems and low-dimensional systems. Notably, despite the 2D nature of the interfacial electron gas, the samples are 3D objects with thickness in the mm range. This prevented researchers so far from adopting strategies that are only viable for fully 2D materials, or from effectively exploiting degrees of freedom related to strain, strain gradient and curvature. Here a method based on pure strain engineering for obtaining freestanding LaAlO3/SrTiO3 membranes with micrometer lateral dimensions is demonstrated. Detailed transmission electron microscopy investigations show that the membranes are fully epitaxial and that their curvature results in a huge strain gradient, each layer showing a mixed compressive/tensile strain state. Electronic devices are fabricated by realizing ad hoc circuits for individual micro-membranes transferred on silicon chips. The samples exhibit metallic conductivity and electrostatic field effect like 2D-electron systems in bulk heterostructures. The results open a new path for adding oxide functionalities into semiconductor electronics, potentially allowing for ultra-low voltage gating of a superconducting transistors, micromechanical control of the 2D electron gas mediated by ferroelectricity and flexoelectricity, and on-chip straintronics.}, annote = {https://doi.org/10.1002/adfm.201909964}, author = {Sambri, Alessia and Scuderi, Mario and Guarino, Anita and Gennaro, Emiliano Di and Erlandsen, Ricci and Dahm, Rasmus T and Bj{\o}rlig, Anders V and Christensen, Dennis V and Capua, Roberto Di and Ventura, Bartolomeo Della and di Uccio, Umberto Scotti and Mirabella, Salvatore and Nicotra, Giuseppe and Spinella, Corrado and Jespersen, Thomas S and Granozio, Fabio Miletto}, doi = {https://doi.org/10.1002/adfm.201909964}, issn = {1616-301X}, journal = {Advanced Functional Materials}, keywords = {LaAlO3/SrTiO3,freestanding membranes,oxide heterostructures,oxides on silicon,strain engineering,strain gradient}, month = {nov}, number = {45}, pages = {1909964}, publisher = {John Wiley & Sons, Ltd}, title = {{Self-Formed, Conducting LaAlO3/SrTiO3 Micro-Membranes}}, url = {https://doi.org/10.1002/adfm.201909964}, volume = {30}, year = {2020} }
