  1. Shown are dielectric permittivity and effective longitudinal piezoelectric response in gamma-irradiated PZT thin films. Data is extracted by fitting Equation (8) to percent change of given functional response measurement vs. radiation dose. Note that values of φ N are multiplied by three orders of magnitude to make interpretation more manageable.
