Journal ArticleDOI
Tuning Dirac states by strain in the topological insulator Bi 2 Se 3
Yang Liu,Yaoyi Li,S. Rajput,D. Gilks,Leonardo Lari,Pedro L. Galindo,Michael Weinert,Vlado K. Lazarov,Lian Li +8 more
TL;DR: Bismuth selenide is a prototypical 3D topological insulator; its electronic spectrum features a Dirac cone populated by surface states, and it is experimentally and numerically shown that a bandgap forms beyond a certain critical compressive strain, destroying the surface states as discussed by the authors.
Journal ArticleDOI
Atomic-scale structure and properties of highly stable antiphase boundary defects in Fe 3 O 4
Keith P. McKenna,Florian Hofer,D. Gilks,Vlado K. Lazarov,Chunlin Chen,Zhongchang Wang,Yuichi Ikuhara +6 more
TL;DR: It is demonstrated that APB defects on the {110} planes are unusually stable and induce antiferromagnetic coupling between adjacent domains providing an explanation for the magnetoresistance and reduced spin polarization often observed.
Journal ArticleDOI
Origin of reduced magnetization and domain formation in small magnetite nanoparticles
Zlatko Nedelkoski,Demie Kepaptsoglou,Leonardo Lari,Tianlong Wen,Ryan Booth,Samuel D. Oberdick,Pedro L. Galindo,Quentin M. Ramasse,Richard F. L. Evans,Sara A. Majetich,Vlado K. Lazarov +10 more
TL;DR: The structural, chemical, and magnetic properties of magnetite nanoparticles are compared and Aberration corrected scanning transmission electron microscopy reveals the prevalence of antiphase boundaries in nanoparticles that have significantly reduced magnetization, relative to the bulk.
Journal ArticleDOI
Structure of the hydrogen-stabilized MgO (111) - (1×1) polar surface: Integrated experimental and theoretical studies
Vlado K. Lazarov,R. Plass,H-C Poon,Dilano K. Saldin,Michael Weinert,Scott A. Chambers,Marija Gajdardziska-Josifovska +6 more
TL;DR: In this article, the surface structure of extremely polar oxide surfaces has been investigated by transmission and reflection high-energy electron diffraction, low-energy ion diffraction (LEED), and x-ray photoelectron and Auger electron difforescence.
Journal ArticleDOI
Surface energies control the self-organization of oriented In2O3 nanostructures on cubic zirconia.
TL;DR: It is shown that the striking influence of substrate orientation on the growth morphology is controlled by differences in energies between the low index surfaces of In(2)O(3) and that spontaneous self-organization is driven by minimization of surface energies.
