Poling tuning: A plausible solution for minimizing microphony and secondary pyroelectric coefficient in ferroelectrics
Source abstract
Abstract
Abstract This study proposes the idea of reducing the microphony effect and secondary pyroelectric coefficient in pyroelectric detectors by tuning the poling orientation. Mathematically, it has been shown that piezoelectric strain coefficients get altered by changing the poling direction. Eventually, for a couple of materials it has been demonstrated that microphony and secondary pyroelectric coefficient can be diminished by poling them at a given orientation. The poling angle nullifying secondary pyroelectric coefficient was found to be 58.2°, 47.1°, and 78.9° for (PZN‐0.08PT), (PMN‐PT), and (BCT‐0.48BZT) respectively while no such value existed for (PZT‐5A).
