| Abstract Scope |
Complex oxides are a class of materials with broad diversity in the structural, chemical and physical characteristics. Pulsed laser deposition (PLD) of complex oxide films has unearthed several of these interesting phenomena and is slowly evolving into a commercially viable technique. The development of high pressure reflection high energy electron diffraction (RHEED) has revolutionized in situ structural characterization during PLD and unleashed atomic scale engineering of oxide heterostructures. In this talk, I will discuss my group’s efforts on implementing an in situ and real time Auger electron spectroscopy for pulsed laser deposition. We have used this method to sense several elements (>25) with monolayer level surface sensitivity. I will also discuss the use of this technique with RHEED to elucidate the dynamics of growth during PLD. I will provide the future outlook for heterostructure engineering and in situ analysis during PLD to discover interesting physical phenomena in complex oxides. |
