Study of dielectric behavior and electrical properties of hematite α-Fe2O3 doped with Zn [PDF]
The effects of Zn-doping on the dielectric behavior and electrical properties of bulk α-Fe2O3 have been studied. X-ray diffraction analysis revealed the presence of two phases in all samples: hematite and spinel ZnFe2O4, with the amount of spinel ...

Dielectric Response of Silica Aerogels [PDF]
The dielectric response of porous silica aerogel prepared by hypercritical drying of gels from hydrolysis of TMOS — Methanol solution have been measured between 1.6 K to 300 K and frequencies between 50 and 10 5 Hz. The ɛ' value of the porous gels is found practically constant between room temperature and 100K but smaller than of fused silica. A sharp

Broadband dielectric response of AlN ceramic composites [PDF]
Aluminium nitride (AlN) is considered as a substrate material for microelectronic applications. AlN ceramic composites with different amount of TiO2 (up to 4 vol.%) were obtained using hot pressing at different sintering temperature from 1700 to 1900 °C ...

Anomalous dielectric response of nanoconfined water [PDF]
In order to develop a microscopic level understanding of the anomalous dielectric properties of nanoconfined water (NCW), we study and compare three different systems, namely, (i) NCW between parallel graphene sheets (NCW–GSs), (ii) NCW inside graphene covered nanosphere (NCW–Sph), and (iii) a collection of one- and two-dimensional constrained Ising ...
