|Title:||Transport pathways for mobile ions in disordered solids from the analysis of energy-scaled bond-valence mismatch landscapes||Authors:||Adams, S.
|Issue Date:||2009||Citation:||Adams, S., Rao, R.P. (2009). Transport pathways for mobile ions in disordered solids from the analysis of energy-scaled bond-valence mismatch landscapes. Physical Chemistry Chemical Physics 11 (17) : 3210-3216. ScholarBank@NUS Repository.||Abstract:||Structure-property relationships provide valuable guidelines for a systematic development of functional materials. Here an augmented bond-valence approach is worked out that is linked directly to the energy scale. This energy-scaled bond-valence approach is then used to identify ion-conduction pathways and to establish structure-property relationships in complex disordered solids using lithium silicate glasses as model systems. Representative local structure models of glassy solid electrolytes as a basis for the pathway analysis are derived from molecular dynamics simulations. Predictions of the bond-valence model from a static structure model are compared to a complete trajectory analysis, showing a high degree of agreement. The method yields consistent results when changing the simulation force field and is applicable to a wide range of glasses. © 2009 the Owner Societies.||Source Title:||Physical Chemistry Chemical Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/86818||ISSN:||14639076|
