CO catalytic oxidation on the two-dimensional (2D) Fe/NX clusters embedded graphene (G) (X = 4, 3, 2, 1) with D4h, C2v, C2h, and CS symmetries is investigated using the first-principle method. Fe/N2-G system with C2h symmetry facilitates the O2 adsorption. The strong interaction between the Fe atom and O2 in Fe/N2-G system can be contributed from the high energy of Fe’s $$d_z^2$$ d z 2 ...
Epitaxial Bi0.9Eu0.1FeO3 (BEFO) thin films are deposited on Nb-doped SrTiO3 (NSTO) substrates by pulsed laser deposition to fabricate the Pt/BEFO/NSTO (001) heterostructures. These heterostructures possess bipolar resistive switching, where the resistances versus writing voltage exhibits a distinct hysteresis loop and a memristive behavior with good retention and anti-fatigue characteristics. The...
