The evolution of ferroelectric domain structure in Remeika-grown BaTiO3 crystals under an inhomogeneous electric field has been investigated using piezoresponse force microscopy. The ac imaging bias was found to affect the metastable polarization state and lead to the formation of a web-like domain structure. It is suggested that this behavior is due to the existence of subsurface domains arising in single crystals with a layered structure.

    Thickness-dependence of coercive field (EC) was investigated in ultrathin BaTiO3 capacitors with thicknesses (d) between 30 and 5.0 nm. The EC appears nearly independent of d below 15 nm, and decreases slowly as d increases above 15 nm. This behavior can be explained not by effects of...

    In IEC 61967 standards, there is often interest to evaluate electromagnetic emission of integrated circuits (ICs) by mounting IC test board on TEM/GTEM cell wall. The method is able to separate the desired emission measurement to be influenced by unintentional interference. However, this method...
