One hundred years after ferroelectricity was first reported [Physical Review 17, 475 (1921)], a qualitatively different phenomenon, asymmetric ferroelectricity, is reported in atomic-scale engineered crystals. Unlike the high-temperature centrosymmet

The main mechanism of energy loss in capacitors with nanoscale dielectric films is leakage currents. Using the example of Al-Al2O3-Al, we show that there are two main contributions, namely the cold field emission effect and the hopping conductivity t

Electric capacitors are commonly used in electronic circuits for short-term storage of small amounts of energy. It is desirable however to use capacitors to store much larger energy amounts to replace rechargeable batteries. Unfortunately, the existi

Microseismicity in subsurface geologic environments, such as sandstone gas reservoirs, is expected in the presence of liquid or gas injection. Although difficult to predict, the potential for microseismic events is important to field-scale projects,

Anomalously large dielectric aging is found in the high-susceptibility plateau ferroelectric regime of ~95% deuterated potassium dihydrogen phosphate (DKDP). Much less aging is found in non-deuterated KDP. Optical images of the DKDP domain structure

Barkhausen current noise is used to probe the slow field-driven conversion of the glassy relaxor ferroelectric state to an ordered ferroelectric (FE) state. The frequent presence of distinct micron-scale Barkhausen events well before the polarization

The anomalously large dielectric aging in ferroelectric partially deuterated potassium dihydrogen phosphate (DKDP) is found to have multiple distinct mechanisms. Two components cause decreases in dielectric response over a limited range of fields aro

Large low-frequency polarization noise is found in some perovskite relaxor ferroelectrics when they are partially polarized, regardless of whether the polarization is accompanied by an applied electric field. The noise appears both in the ferroelectr

Polarization and transmission electron microscopy studies of the Pb0.97La0.02(Zr0.65Sn0.22Ti0.13)O3 (PLZST) ceramics confirmed the antiferroelectric (AFE) nature of this material. The electric-field-induced ferroelectric (FE) phase has a lifetime muc

The bias field-temperature, E-T, phase diagram for 0.87PbMg 1/3 Nb 2/3 O 3 -0.13PbTiO 3 crystals has been obtained by using two different techniques, dielectric spectroscopy and elastic compliance. The temperature dependence of both the dielectric pe
