In oxide literature, the term is commonly used to refer to any oxide with at least five principal cations. However, it has been suggested that this is a misnomer, as most reports neglect to calculate configurational entropy. Additionally, a survey of 10 HEOs found that only 3 were entropy-stabilized. It has been suggested that the term HEO be replaced with three terms: compositionally complex oxide, high-entropy oxide, and entropy-stabi… green day tv shows
