Electrochemical Synthesis of Ethyl-Substituted Alkylammonium-Intercalated β-FeSe Superconductors with T c up to 44 K

Abstract The intercalation of organic cations into superconducting iron selenide can significantly enhance the critical temperature (Tc). We investigated the electrochemical intercalation of ethyltrimethylammonium (ETMA+) and diethyldimethylammonium (DEDMA+) cations into β-FeSe,...
