Miscellaneous Information

Staff Researcher at the Institute for Superconductors, oxides and other innovative materials and devices (SPIN) of the National Council of Research (CNR),  Unity of Naples;

 

Research activity

My research activity is focused on the fabrication and characterization of epitaxial, nanostructured or amorphous thin films and/or multilayers, mainly of perovskite oxides. In particular, I worked on the fabrication and characterization, by means of several techniques (XRD, AFM, PFM, electrical and ferroelectrical measurements, synchrotron facilities) of: i) samples of LaAlO₃/SrTiO₃ and LaGaO₃/SrTiO₃ for the study of two-dimensional electronic gases at the interface between two insulators; ii) epitaxial samples of Pb(Zr_0.2Ti_0.8)O₃/SrRuO₃/SrTiO₃/Si for the integration of ferroelectric perovskites on silicon and the realization of epi-piezo MEMS; iii) new types of multilayers based on LaAlO₃/SrTiO₃ interfaces coupled with magnetic (EuTiO₃, LaSrMnO₃) and/or ferroelectric (BaTiO₃) oxide films; iv) of graphene/LaAlO₃/SrTiO₃ hybrid systems; iv) fabrication and characterization of ferroelectric compounds with low band-gap thin films, for application in photo-ferroelectric materials based tandem solar cells.

Recently, an important part of my research deals with "LaAlO₃/SrTiO₃ free-standing (super)conducting epitaxial micro-heterostructures" fabricated by PLD through an innovative method based on pure strain engineering, developed for the first time in CNR-SPIN labs of Naples and described in "Sambri et al., Adv. Func. Mat. 30, 1909964 (2020)", followed by a Patent application (see below for details). The discovered method opened up a completely new research line, currently very active in a international framework of collaborations.
