Vibrational analysis and AC electrical conduction behavior of lithium zinc orthogermanate

Synthesis, optical and ionic conductivity studies of a lithium cobalt germanate compound

“…The powder structure of Li 2 CoGeO 4 indicates that it is isostructural like the Li 2 ZnGeO 4 structure. 9 The framework structure of Li 2 CoGeO 4 host can be considered as a Wurtzite structure with corner-sharing alternating between the corners of the GeO 4 and ZnO 4 tetrahedra. In general, the orthogermanates are characterized by tetrahedral anion units, in particular (GeO 4 ) 4 , covalently connected to the BO 4 polyhedra.…”

“… 8 S. Ben Yahya and B. Louati have studied the electric properties of A 2 ZnGeO 4 (A = Li and K) compounds. 9,10 They have determined the electrical conductivity of these materials and estimated them: 10 −3 (Ω m) −1 and 10 −5 (Ω m) −1 for K 2 ZnGeO 4 and Li 2 ZnGeO 4 respectively. In this work Li 2 CoGeO 4 (LCG) is studied.…”

“…Furthermore, Urbach's energy results align well with the entropy results obtained in the previous thermodynamics section. 7,8 3.5. Ellipsometric investigation of A 2 ZnGeO 4 (A = K, Li) Spectroscopic ellipsometry (SE) is a technique to measure the changes in polarization of light as it reects off a surface.…”

Synthesis, morphological, electrical, and conduction mechanism studies of a sodium cerium diphosphate compound

“…The average crystallite size of the NaCeP 2 O 7 was calculated using the Debye–Scherrer formula: 25 where the θ and β are the diffraction angle and the half-height width (FWHM) of the diffraction peak, respectively; λ is the wavelength of the copper radiation ( λ Kα = 1.5406 Å). To determine the value of the crystalline size, we need to conduct Lorentzian fit on the most intense peak of the XRD pattern, which was located at 2 θ = 27.75°.…”
