Epitaxial formation of ultrathin HfO2 on graphene by sequential oxidation
Zhenjing Liu, Qian Mao, Varun Kamboj +6
We demonstrate the formation of epitaxial, ultrathin hafnia (HfO2) on graphene. Monoclinic hafnia (m-HfO2) forms as the end of a series of sequential oxidation reactions. Starting…

Electrochemically induced switching from antiferromagnetic spin-chain to frustrated spin-glass state in maple-leaf lattice Na2Mn3O7
Corson Chao, Shivani Srivastava, Ming Lei +9
We report the electrochemical tuning of magnetic properties in the Na2Mn3O7 maple-leaf lattice (MLL) through ion deintercalation, revealing a switch from the 1D antiferromagnetic (…
