Abstract:

The ionic conductivity at 100 C of lithium borate glasses doped with lithium sulfate is found experimentally to decrease by three orders of magnitude when the annealing temperature is increased from 515 C to above the crystallization temperature of 532 C. This behavior is correlated with structural changes investigated by Raman spectroscopy. Under suitable conditions, lithium metal can be intercalated into the layered compound InSe. Experimental data for the resistivity as a function of time of intercalation is presented. A simple model is developed to explain the transfer of electrons from the lithium atoms to the InSe layers and is used to quantitatively relate the fraction of electrons transferred to the potential well depth of the InSe. Experimental photoluminescence data for lithium intercalated InSe are presented and interpreted in terms of excitons bound to the Li atoms.
