Deterministic Control of Sn3+ Valence and Electronic Phase Evolution in AgSnSe2
: Understanding how unusual oxidation states influence material properties is important for both fundamental science and energy applications. AgSnSe 2 is particularly intriguing because it stabilizes the rare and long-debated Sn 3+ oxidation state, whose true existence and role have remained enigmatic for many years. I...
