Electrical conductivity, thermoelectric power and dielectric constant of a Gd2Ti2O7 single crystal have been studied in the temperature range 300–1000 K. Gd2Ti2O7 is found to be an-type semiconductor with energy band gap 1.5 eV. It exhibits an extrinsic nature up to 675 K and an intrins...
Hydrochloric acid (HCl) and isopropanol (IPA) were purchased from Beijing Institute of Chemical Industry and Guangdong Guanghua Technology Co., Ltd. respectively. The above raw materials were used Structure characterization of h-BN and BNNS The SEM and AFM images of h-BN (before peeling) and ...
While for the realistic energy storage of capacitors, a bottle-neck challenge is how to maximally enhance the εr and simultaneously keep a high Eb (>400 MV/m)) [23,24]. Because the working electrical field (Eworking) of the capacitor is a constant high value [36], such as 200 MV/...

Here,ε∞is the high-frequency dielectric constant,Cis the Curie constant andTCis the Curie temperature. The low-temperature wing of the maximum reveals a pronounced frequency dispersion that is caused by a relaxational band (Fig.2b, c) signified by a typical relaxation step inε′(ν) togethe...
All the KTNO samples of varying compositions exhibit high dielectric permittivity (~104) near room temperature, which is comparable to that of the recently discovered CaCu3Ti4O12 (CCTO) ceramic. The high dielectric constant of KTNO depends on both the K and Ti content and can be attributed ...
wherein the dielectric constant is a relative scale in which a vacuum is defined as having a dielectric constant of about 1. As the line width in the devices decreases to 0.13 microns and below, significant decreases in the dielectric constant of the interlayer dielectric material will be requir...
Microwave measurements show a negative dielectric constant for the more metallic of the PAN-CSA samples./sup 2/ Analysis of the energy loss function also shows a clear plasma resonance peak at ~1.1 eV, unlike non-stretched PAN-HCl materials. Additionally, the loss function shows stronger phonon...
