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
