Atomic-Scale Quantitative Analysis of Lattice Distortions at Interfaces of Two-Dimensionally Sr-Doped La2CuO4 Superlattices

Using spherical aberration corrected high-resolution and analytical scanning transmission electron microscopy, we have quantitatively studied the lattice distortion and the redistribution of charges in two-dimensionally strontium (Sr)-doped La2CuO4 superlattices, in which single LaO planes are periodically replaced by SrO planes. As shown previously, such structures show Tc up to 35 K as a cons...

Oxygen interstitials in superconducting La2CuO4: their valence state and role.

The nature of the much debated valence state of an interstitial oxygen atom in oxygen-doped La2CuO4 is the subject of this paper. In model cluster calculations, we studied the position, charge, and spin state of the interstitial oxygen atoms in this superconductor. The models considered allow the interstitial oxygen to move off a symmetrical position, to have varying spin and charge, and to be ...

Calculation of dopant segregation ratios at semiconductor interfaces

We analyzed dopant segregation at semiconductor interfaces by equilibrating chemical potentials of dopants and electrons on each side of the interface. We apply the theory to Si/strained-SiGe interfaces and compare the predictions with existing experimental data. The calculations include changes in effective density of states with particular attention to high-temperature hole effective mass , b...

Ferroelectricity in underdoped La-based cuprates

Doping a "parent" antiferromagnetic Mott insulator in cuprates leads to short-range electronic correlations and eventually to high-Tc superconductivity. However, the nature of charge correlations in the lightly doped cuprates remains unclear. Understanding the intermediate electronic phase in the phase diagram (between the parent insulator and the high-Tc superconductor) is expected to elucidat...

Enzymatic cross-linking at oil-water interfaces – a rheological study

Potential food-compatible technologies for novel oil-in-water emulsions include interfacial cross-linking by enzymatic means. The objective of the present research is to elucidate the mechanisms, by which protein interfaces control transfer of low molecular weight compounds. As a first step, the impact of enzymatic cross-linking on mechanical properties of -casein layer was studied. The depende...
