Construction of oxide-carbide artificial superlattices using C-60-assisted pulsed-laser-deposition technique
Epitaxially oriented artificial superlattices which consist of an oxide (MgO) and a carbide (TiC) were fabricated oil an MgO(001) substrate using the pulsed-laser-deposition (PLD) technique. TiC layers were fabricated by the PLD of a Ti metal target with a coevaporation of C-60, while the MgO layers were fabricated by the PLD of an MgO target under ail oxygen atmosphere. The thickness of each layer was controlled from 20 to 5 atomic layers. X-ray diffraction patterns show defined long-periodic superlattice peaks and satellite peaks at expected diffraction angles. Cross-section transmission electron microscope analysis demonstrates the presence of the alternate stacks of each layer with layer-by-layer crystal growth, while secondary ion mass spectroscope analysis clearly proves the alternate stacks of MgO a TiC layers.
