(author)Shubnikov–de Haas oscillations for two well-defined frequencies, corresponding, respectively, to areas of 0.8 and 1.36% of the first Brillouin zone, were observed in single crystals of Na0.3CoO2. The existence of Na superstructures in Na0.3CoO2, coupled with this observation, suggests the possibility that the periods are due to the...journal article 2006

Zandbergen, H.W. (author), Van Tendeloo, G. (author)High-resolution electron microscopy shows that Pb2Sr2(Ca,Y)Cu3O8+? is sensitive to air at room temperature. Planar defects are induced by exposure to air. These planar defects are due to a depletion of Pb and Cu from the three-layer block: PbO-Cu?-PbO, ? being a vacancy. Once these blocks are depleted, further depletion is enhanced, leading to...journal article 1989

Klimczuk, T. (author), Xu, Q. (author), Morosan, E. (author), Thompson, J.D. (author), Zandbergen, H.W. (author), Cava, R.J. (author)Mg10Ir19B16, a previously unreported compound in the Mg-Ir-B chemical system, is found to be superconducting at temperatures near 5 K. The fact that the compound exhibits a range of superconducting temperatures between 4 and 5 K suggests that a range of stoichiometries is allowed, though no structural evidence for this is observed. The compound...journal article 2006

Fang, C.M. (author), Sluiter, M.H.F. (author), Van Huis, M.A. (author), Ande, C.K. (author), Zandbergen, H.W. (author)A long-standing challenge in physics is to understand why cementite is the predominant carbide in steel. Here we show that the prevalent formation of cementite can be explained only by considering its stability at elevated temperature. A systematic highly accurate quantum mechanical study was conducted on the stability of binary iron carbides....journal article 2010

(author)Sputter deposition of oxide materials in a high-pressure oxygen atmosphere is a well-known technique to produce thin films of perovskite oxides in particular. Also interfaces can be fabricated, which we demonstrated recently by growing LaAlO3 on SrTiO3 substrates and showing that the interface showed the same high degree of epitaxy and atomic...journal article 2015

(author)Transmission electron microscopy (TEM) of (de-)hydrogenation reactions is crucial to characterize efficiency of hydrogen storage materials. The nanoreactor, a micromachined channel with 15-nm-thick windows, effectively confines the gas flow to an electron-transparent chamber during TEM of reactions. Realistic experiments require very high...journal article 2012

(author)The structural misfit compound (PbSe)1.16(TiSe2)2 is reported. It is a superconductor with a Tc of 2.3 K. (PbSe)1.16(TiSe2)2 derives from a parent compound, TiSe2, which shows a charge-density wave transition and no superconductivity. The crystal structure, characterized by high-resolution electron microscopy and powder x-ray diffraction,...journal article 2010

(author)Nb12O29 is a 4d transition metal oxide that occurs in two forms with different symmetries, monoclinic (m) and orthorhombic (o). The monoclinic form has unusual magnetic properties; below a temperature of 12 K, it exhibits both metallic conductivity and antiferromagnetic ordering. Here, first-principles density-functional theory calculations are...journal article 2014
