On the giant deformation and ferroelectricity of guanidinium nitrate.

The article in Nature Communications discusses the properties of guanidinium nitrate (GN) and challenges the claims made by Karothu et al. regarding the ferroelectricity and semiconductivity of GN crystals. The authors present evidence from previous studies on the giant deformation, crystal structures, and dielectric properties of GN to refute the new properties claimed by Karothu et al. They conclude that GN does not exhibit ferroelectric properties and is unsuitable for certain applications proposed by Karothu et al. The study was supported by the Adam Mickiewicz University in Poznań and the authors declare no competing interests. [Extracted from the article]
