The contribution from the irreversible displacement of non-180 degrees domain walls to the direct longitudinal piezoelectric d(33) coefficient of BaTiO3 and Pb(Zr,Ti)O-3 ceramics was determined quantitatively by using the Rayleigh law. Effects of the cryst ...
Aquaporins form a large family of membrane channels involved in osmoregulation, Electron crystallography has shown monomers to consist of six membrane spanning a-helices confirming sequence based predictions. Surface exposed loops are the least conserved r ...
We report on angle-resolved photoemission and superconductor-insulator-superconductor tunneling measurements of the normal and superconducting states of Bi2Sr2CaCu2O8+x single crystal samples and Bi2Sr2CaCu2O8+x - native oxide- lead (S-I-S) tunnel junction ...
The structural phases observed in LiKSO4 crystals due to thermotropic transitions have been studied for more than a century. Nowadays many different phases are referenced, but some of the results are still controversial. Structural studies by single-crysta ...
High-resolution angle-resolved photoemission and core-level photoemission measurements were performed on single crystal samples of the quasi-one-dimensional material (TaSe4)(2)I and the cuprate superconductor Bi2Sr2CaCu2O8+x. Resistivity measurements were ...
We have exploited angle-resolved photoelectron spectroscopy (ARPES) to study the electronic structure of single crystal samples of high T-c material Bi2Sr2CaCu2O8+delta and of the antiferromagnetic insulator Sr2CuO2Cl2. As one moves away from optimal dopin ...
We review the current theory of intrinsic dielectric loss, that is the loss in a perfect crystal due to anharmonic interaction of a.c. electric field with the phonon system of the crystal. Both ordinary dielectrics and displacive ferroelectrics are conside ...
