Quantitative calculations of charge carrier densities in the depletion layers at YBa2Cu3O7-x interfaces
U. Schwingenschloegl, C. Schuster
Charge redistribution at high-Tc superconductor interfaces and grain boundaries on the one hand is problematic for technological application. On the other hand, it gives rise to a…
Exponential decay of relaxation effects at LaAlO3/SrTiO3 heterointerfaces
U. Schwingenschloegl, C. Schuster
We study the decay of interface induced structural and electronic relaxation effects in epitaxial LaAlO3/SrTiO3 heterostructures. The results are based on first-principles band str…
Polar catastrophe and electronic reconstructions at the LaAlO3/SrTiO3 interface: evidence from optical second harmonic generation
A. Savoia, D. Paparo, P. Perna +8
The so-called "polar catastrophe", a sudden electronic reconstruction taking place to compensate for the interfacial ionic polar discontinuity, is currently considered as a likely…
Colossal dielectric constant up to GHz at room temperature
S. Krohns, P. Lunkenheimer, Ch. Kant +5
The search for new materials with extremely high ("colossal") dielectric constants, required for future electronics, is one of the most active fields of modern materials science. H…
Colossal magnetocapacitive effect in differently synthesized and doped CdCr2S4
S. Krohns, F. Schrettle, P. Lunkenheimer +2
In the present work, we address the question of an impurity-related origin of the colossal magnetocapacitive effect in the spinel system CdCr2S4. We demonstrate that a strong varia…
Spin Frustration and Magnetic Exchange in Cobalt Aluminum Oxide Spinels
N. Tristan, V. Zestrea, G. Behr +5
We report on x-ray diffraction, magnetic susceptibility, electron- spin resonance and heat- capacity studies of Co[Al_1-xCo_x]_2O_4 for Co concentrations 0<x<1. In this spinel syst…
