Influence of protons doping on physical properties of li2ge7o15 crystals

الملخص EN

This research shows that lithium heptagermanate crystals (Li2Ge7O15) can be doped by protons during annealing in benzene carboxylic acid.

The presence of proton doping by the above method was proved by the IR-absorption spectrum and also by the weak shift of Tc toward lower temperature.

Proton doping leads to a reduction in both the dielectric permittivity at Curie point and optical transmission in the visible region.

Proton doping also increased the conductivity (almost in one order of magnitude) of LGO crystal in [001] direction.
