Abstract
Subject headings
Close
- Multilayered Al/Cu/Co thin films have been prepared by magnetron sputtering on Al2O3(0001) and Si(001) substrates and the phase evolution has been investigated. The decagonal d-Al-Cu-Co and d-Al-Cu-Co-Si phases were found to form at 500 °C, and at 600 °C these were the only phases. At increasing temperatures, the quasicrystals grew larger in size, up to 500 nm, although always smaller for the d-Al-Cu-Co-Si, and obtained a texturing with the 10-fold periodic axis aligned with the substrate normal. The d-Al-Cu-Co phase persisted to more than 850 °C, with a complete texturing, while the d-Al-Cu-Co-Si phase was replaced by other crystalline phases at 800 °C.
