Effects of Pb doping on structural and electronics properties of Bi$_2$Sr$_2$Ca$_2$Cu$_3$O$_{10}$
, 2015 Pb doping effect in the Bi$_2$Sr$_2$Ca$_2$Cu$_3$O$_{10}$ compound (Bi2223) on the structural and electronic properties were investigated, using the Local Density (LDA) and Virtual Crystal (VCA) approximations within the framework of the Density ...

Structural Control on the Formation of Pb-Zn Deposits: An Example from the Pyrenean Axial Zone
Minerals, 2018 Pb-Zn deposits and specifically Sedimentary-Exhalative (SEDEX) deposits are frequently found in deformed and/or metamorphosed geological terranes. Ore bodies structure is generally difficult to observe and its relationships to the regional structural ...

Reversible shift in the superconducting transition for La1.85Sr0.15CuO4 and BaFe1.8Co0.2As2 using piezoelectric substrates [PDF]
, 2010 The use of piezoelectric substrates enables a dynamic observation of strain dependent properties of functional materials. Based on studies with La1.85Sr0.15CuO4 we extended this approach to the iron arsenic superconductors represented by BaFe2-xCoxAs2 to

Structural transitions in Pb(In1∕2Nb1∕2)O3 under pressure [PDF]
Journal of Advanced Dielectrics, 2015 Room-temperature Raman scattering and x-ray diffraction measurements together with first-principles calculations were employed to investigate the behavior of disordered Pb(In1∕2Nb1∕2)O3 (PIN) under pressure up to 50GPa. Raman spectra show broad bands but

Charge transfer electrostatic model of compositional order in perovskite alloys
, 2000 We introduce an electrostatic model including charge transfer, which is shown to account for the observed B-site ordering in Pb-based perovskite alloys. The model allows charge transfer between A-sites and is a generalization of Bellaiche and Vanderbilt ...

Evolution of Structure and Superconductivity in Ba(Ni$_{1-x}$Co$_x$)$_2$As$_2$ [PDF]
, 2018 The effects of Co-substitution on Ba(Ni$_{1-x}$Co$_x$)$_2$As$_2$ ($0\leq x\leq 0.251$) single crystals grown out of Pb flux are investigated via transport, magnetic, and thermodynamic measurements.

Structural model of silicene-like nanoribbons on a Pb-reconstructed Si(111) surface
Beilstein Journal of Nanotechnology, 2017 A structural model of the recently observed silicene-like nanoribbons on a Pb-induced √3 × √3 reconstructed Si(111) surface is proposed. The model, which is based on first principles density functional theory calculations, features a deformed honeycomb ...

Quantum size effects in the low temperature layer-by-layer growth of Pb on Ge(001)
, 2003 The electronic properties of thin metallic films deviate from the corresponding bulk ones when the film thickness is comparable with the wavelength of the electrons at the Fermi level due to quantum size effects (QSE). QSE are expected to affect the film
