Abstract

In case of the cube textured (CUTE) Ag substrate, recrystallization process of as-rolled Ag substrate in various atmosphere changed surface flatness of the substrate. When the substrate was heated in a vacuum chamber with a oxygen partial pressure of less than 1 × 10^-5 Torr at 600°C, the surface average roughness (R_a) of the substrate was less than 120 nm. Then the oxygen was introduced into the vacuum chamber to fabricate CeO₂ buffer layer on the substrate by pulsed laser deposition. After the oxygen pressure reached to 50-150 mTorr, CeO₂ layer was deposited on the CUTE Ag substrate immediately. By reducing the influence of oxygen to surface roughness of the substrate, R_a of the CeO₂ buffered CUTE Ag substrate was 30 nm.
