Designing antiphase boundaries by atomic control of heterointerfaces.
Zhen Wang,Zhen Wang,Hangwen Guo,Shuai Shao,Mohammad Saghayezhian,Jun Li,Rosalba Fittipaldi,Antonio Vecchione,Prahald Siwakoti,Yimei Zhu,Jiandi Zhang,E. W. Plummer +11 more
TL;DR: This work reports an approach to create planar extended defects—antiphase boundaries (APB) —with well-defined origins via the combination of advanced growth, atomic-resolved electron microscopy, first-principals calculations, and defect theory.

Cr-Doped TiSe2 - A Layered Dichalcogenide Spin Glass
Huixia Luo,Jason W. Krizan,Elizabeth M. Seibel,Weiwei Xie,Girija Sahasrabudhe,Susanna L. Bergman,Brendan F. Phelan,Jing Tao,Zhen Wang,Jiandi Zhang,R. J. Cava +10 more
TL;DR: In this paper, the magnetic properties of the Cr-doped layered dichalcogenide TiSe2 have been investigated and it has been shown that the temperature dependent magnetic susceptibilities are typical of those seen in geometrically frustrated insulating antiferromagnets.
Anomalously deep polarization in SrTiO3 (001) interfaced with an epitaxial ultrathin manganite film
Zhen Wang,Zhen Wang,Jing Tao,Liping Yu,Hangwen Guo,Lina Chen,Myung-Geun Han,Lijun Wu,Huolin L. Xin,Kim Kisslinger,E. W. Plummer,Jiandi Zhang,Yimei Zhu +12 more
TL;DR: In this article, the authors reveal a remarkably deep polarization in nonferroelectric transition metal oxides near its interface with an ultrathin nonmetallic film of the same type.
Manipulating the polar mismatch at the LaNi O 3 /SrTi O 3 (111) interface
TL;DR: In this paper, the structure of transition-metal oxide films from interface to the surface has been studied and it was shown that proper processing can lead to a structure that is ordered, coherent with the substrate without intermediate structural phase Angle-resolved x-ray photoemission spectroscopy shows that the oxygen content of thin films increases with the film thickness, indicating that the polar mismatch is avoided by the presence of oxygen vacancies.

Interrogating the superconductor Ca10(Pt4As8)(Fe2-xPtxAs2)5 Layer-by-layer
Jisun Kim,Hyoungdo Nam,Guorong Li,Amar B. Karki,Zhen Wang,Yimei Zhu,Chih-Kang Shih,Jiandi Zhang,Rongying Jin,E. W. Plummer +9 more
TL;DR: In this article, the electronic properties of individual layers were studied using scanning tunneling microscopy/spectroscopy (STM/S), which reveals different spectra for each surface.
