Friedel oscillations and helium bubble ordering in molybdenum
W. T. Geng, Q. Zhan
Helium ions implanted into metals can evolve into ordered bubbles isomorphic to the host lattice. Long-range elastic interaction is generally believed to drive the formation of bub…
One-for-multiple substitution in solid solutions
W. T. Geng, Q. Zhan
It is generally assumed that one solute atom will occupy only one lattice site in a substitutional solid solution. We here report an interesting discovery by first-principles calcu…
Waltzing of a Helium Pair in Tungsten: Migration Barrier and Trajectory Revealed from First-Principles
J. G. Niu, Q. Zhan, W. T. Geng
Despite well documented first-principles theoretical determination of the low migration energy (0.06 eV) of a single He in tungsten, fully quantum mechanical calculations on the mi…
Local Conduction at the BiFeO3-CoFe2O4 Tubular Oxide Interface
Ying-Hui Hsieh, Jia-Ming Liou, Bo-Chao Huang +6
In strongly correlated oxides, heterointerfaces, manipulating the interaction, frustration, and discontinuity of lattice, charge, orbital, and spin degrees of freedom, generate new…
Anomalously large measured thermoelectric power factor in SrLaTiO thin films due to SrTiO substrate reduction
Matthew L. Scullin, Choongho Yu, Mark Huijben +6
We report the observation that thermoelectric thin-films of La-doped SrTiO3 grown on SrTiO3 substrates yield anomalously high values of thermopower to give extraordinary values of…
Reversible Structural Transition in Epitaxial Manganite Film
Q. Zhan, R. Yu, L. L. He +4
A reversible structural transition of an epitaxial La2/3Sr1/3MnO3 film deposited on the LaAlO3 substrate has been investigated by means of in situ high-resolution transmission elec…
