Temperature dependent mechanical property of PZT film: an investigation by nanoindentation.

PLoS ONE, 2015
Load-depth curves of an unpoled Lead Zirconate Titanate (PZT) film composite as a function of temperature were measured by nanoindentation technique. Its reduce modulus and hardness were calculated by the typical Oliver-Pharr method.
