Synthesis and investigation of the morphological, optical, electrical and dielectric characteristics of a disodium cobalt orthogermanate
A sodium cobalt germanate material (Na 2 CoGeO 4 ) was synthesized and studied. The X-ray powder diffraction pattern revealed a monoclinic crystal system with the Pn space group. The calculated value of the direct bandgap ( E g ) was (3.89 ± 0.02) eV. Electrical measurements were undertaken in a fre...

was associated with the correlated barrier hopping (CBH) model. Studies of the complex electric modulus

) confirmed that the relaxation process was thermally activated.
