Phase fraction of ferroelectric Hf0.5Zr0.5O2 film regulated by the co-action of Ce doping and oxygen defects: First principles study

In this work, the effects of cerium doping and oxygen defects of ferroelectric Hf0.5Zr0.5O2 (HZO) are systematically studied by first-principles calculations. According to the results, the combined effect of Ce atoms and oxygen vacancy has a significant effect on the improvement of the orthorhombic...
