Abstract:A crystalline Bi 2 Ti 2 O 7 (B 2 T 2 ) film with a high dielectric constant (e r ) of 67.2 was formed even at 300 C when the oxygen pressure (OP) exceeded 600 mTorr, even though the Bi 4 Ti 3 O 12 target was used. The Mn-doping improved the electrical properties of the B 2 T 2 films by producing the doubly ionized, extrinsic oxygen vacancies, which reduced the number of intrinsic oxygen vacancies. The B 2 T 2 film containing 20 mol% of Mn ions, which was annealed under an OP of 75.0 Torr, exhibited a low leaka… 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.
