Research background
I am a material scientist and my work focuses mainly on the rich spectrum of properties exhibited by complex transition metal perovskite oxides and their interfaces. In the lab I deal with several techniques, and I have gained the following expertises:
- Growth and characterization of functional oxide thin films.
- Pulsed laser deposition, thermal evaporator for metals, AFM-PFM-MFM, XRD, magneto-transport system, SQUID, XPS and Sputtering systems
- Synchrotron-based techniques including XLD, XMCD, ARPES, PEEM and REXS/RIXS.
- UV-lithography and chemical/dry etching

Current research
My research is largely focused on the study of the complex physics emerging at the interface between two strongly correlated oxides. I mainly work on rare-earth nickelates/ferroelectric heterostructures and on Sr-doped infinite-layer nickelate thin films. I also exfoliate those thin films by means of a water soluble sacrificial layer and twist them to create novel Moiré interfaces. Very recently, I have started to grow also bilayer Ruddesleden-Popper nickelates under large compressive strain to stabilize a very volatile superconducting state.
