Paper Abstract

Multi-cation oxides with crystalline perfection known from single crystals of Si or Ge are a challenge not only for basic research but also towards a revolution of oxide electronic materials. Here, we present our approach for the synthesis of high-quality thin films of multi-cation oxides. We show that our synthesis method, using state-of the-art molecular beam epitaxy (MBE), facilitates for the design of new materials. We geared our MBE system with a precise rate control system of each constituent cation flux as well as activated oxygen (O*) and ozone (O3). The resulting performances of our MBE setup are unmatched with respect to high-quality film growth as well as multi-cation flexibility by demonstrating growth of various cuprate-, scandate-, argentate-, titanate-, and ruthenate thin films. Such augmented methods are key to novel materials and go well beyond the artificial stacking of known materials and lattices.
