Polar metals: principles and prospects
S Bhowal, NA Spaldin - Annual Review of Materials Research, 2023 - annualreviews.org
We review the class of materials known as polar metals, in which polarity and metallicity
coexist in the same phase. While the notion of polar metals was first invoked more than 50 …
