• Polarization in wurtzite nitrides is a vector quantity whose sign and magnitude depend on coordinate conventions and reference choices, leading to potential ambiguities in device simulations.
• Recent experimental re-benchmarking of giant polarization in ferroelectric nitrides has provided self-consistent, experimentally validated values that correct previous inconsistencies.
• Unified polarization benchmarks enable more predictive engineering of heterostructures and devices, particularly for GaN-based power and RF electronics.
• Standardized polarization language is critical for accurate band diagrams, carrier distributions, and design rules in nitride semiconductor technology.
