Research Abstract

Well-aligned CeO2 nanocrystalline monolayer was successfully fabricated through self-assembly of the nanocrystals for using individual nanocrystals as a nanoscale substrate for epitaxial growth. We confirmed that anatase-type TiO2 was selectively nucleated and epitaxially grown on individual CeO2 nanocrystals after sputtering and successive annealing. It results in fabricating of tandem nanocrsytals with steep interfaces between TiO2{004} and CeO2{002} facets.
