- 摘要：
- The interface strength of Pb(Zr,Ti)O3 (PZT) thin films on a silicon substrate is studied experimentally and theoretically
in this work. The focus is put on crack initiation from the free edge of the interface. A novel method of sandwiched
cantilever specimen is utilized to perform the delamination tests. Theoretical analyses are performed on the
singular behavior of the stress in the vicinity of the free edge along the interface between Cr layer and PZT layer,
and on the distribution of normal stress at the delamination loads. Based on these results, a delamination criterion
involving stress intensity parameter is adopted to estimate the interface toughness for crack initiation at the free edge
along the interface Cr/PZT.
