Correct Implementation of Polarization Constants in Wurtzite Materials and Impact on III-Nitrides
Correct Implementation of Polarization Constants in Wurtzite Materials and Impact on III-Nitrides
Accurate values for polarization discontinuities between pyroelectric materials are critical for understanding and designing the electronic properties of heterostructures. For wurtzite materials, the zincblende structure has been used in the literature as a reference to determine the effective spontaneous polarization constants. We show that, because the zincblende structure has a …
