摘要

阻抗谱数据表明，插层AgxHfS2样品介电常数的实、虚分量存在明显的频散。利用模形式确定了介质弛豫时间，其大小随样品中银含量的增加而减小。它们与由复阻抗虚部的频率依赖性确定的弛豫时间一致。关键词:中间层，阻抗，二硫化铪，银，介电常数，电模块。

Dispersion of dielectric permittivity and electrical modulus in Ag-=SUB=-x-=/SUB=-HfS-=SUB=-2-=/SUB=- compounds with a layered structure

According to the impedance spectroscopy data, a significant frequency dispersion of the real and imaginary components of the permittivity was found in the intercalated AgxHfS2 samples. Using the modular formalism, the dielectric relaxation times were determined, which decrease in magnitude with an increase in the silver content in the samples. Their coincidence with the relaxation times determined from the frequency dependences of the imaginary parts of the complex impedance was shown. Keywords: Intercalates, impedance, hafnium disulfide, silver, dielectric permittivity, electrical module.
