Abstract:Alkali metals undergo an electride transition with excess electrons localized into interstices and acting as anionic interstitial quasi-atoms (ISQs). Less is known about the role of electride transition in changing their thermophysical properties. Here, taking potassium as an example, we investigated the thermodynamic and dynamic properties in the fcc phase region where an electride transition occurs when increasing pressure. With the help of machine-learning enhanced molecular dynamic simulations and DFT calc… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
