An expression is obtained for the dielectric constant of a displacive ferroelectric in its unpolarized phase. This has been derived with the use of a Hamiltonian treated by Szigeti in connection with the temperature-dependent dielectric constant of the alkali halides. In the present work, however,...

The dielectric function[Math Processing Error]of monolayer molybdenum diselenide (MoSe2) is obtained and analyzed at temperatures from 31 to 300 K and at energies from 0.74 to 6.42 eV. The sample is a large-area, partially discontinuous monolayer (submonolayer) film of MoSe2grown on a s...
The ferroelectric to para-electric phase transition in Pb5Ge3O11 has been induced with hydrostatic pressure. The pressure coefficient of the transition temperature, Tc, dTc/dp has been shown to be -15.5°C/kbar. The effects of temperature and pressure on the dielectric properties have been meas...
abasically there are two kinds of supplier selection problem 基本上有二供应商选择问题 [translate] aFigure 1 shows a temperature (T) dependence of the dielectric constant (er) at 10 kHz.Pure SrTiO3 shows a typical quantum paraelectric behavior, er is high but almost temperature independent at ...
For the effect of sintering temperature on the dielectric property, the results showed that the dielectric constants increase with the increase of sintering temperature, which can be mostly associated with the variety of sample density. However, the dielectric losses of both ceramics show a little ...
The dielectric and pyroelectric properties of polar glass cermics Ba2TiSi2O8 and Sr2TiSi2O8 are investigated from 10K to 300K. The pyroelectric coefficient of Ba2TiSi2O8is - 7. 0 ×10-6C/m2· K at room temperature and keeps a relatively high value at low temperature. On the contrary,...
7 reviewed the temperature dependence of the dielectric properties, thermal properties, and perfusion of biological tissues at hyper-thermic and ablation temperatures. Poor et al.8 focused on the temperature disturbance of skin tissue due to time-dependent surface heating. Tzou's model has been ...
Microwave dielectric ceramics of BiLnLiVMoO(Ln = Sm, Nd and La) with a low firing temperature were prepared via conventional solid-state reaction. The phases and microstructures of the ceramics were characterized by x-ray diffraction and scanning electron microscopy. The temperature coefficients of ...
