| description | Silver doped hydroxyapatite (Ag-HAp (2 mol.%)) nanoparticles of crystallite size 43 nm have been synthesized by employing facile hydrothermal method. The structural, morphological, compositional and electrical characteristics have been studied. The detail dielectric properties at and above room temperature shows a high permittivity value of the synthesized material with a very low dielectric loss which is very much promising for future electronic applications. The high temperature real dielectric response curves are least square fitted with modified Cole-Cole equation to observe the agreement between theoretical and experimental values. The correlated barrier hopping (CBH) model prevails the charge transport mechanism within Ag-HAp on application of external electric field. The plot of frequency dependent imaginary electric modulus of our material shows deviation from ideal Debye-type relaxation nature. |
