Contributions to the mixed-alkali effect in molecular dynamics simulations of alkali silicate glasses
Heiko Lammert, Andreas Heuer
The mixed-alkali effect on the cation dynamics in silicate glasses is analyzed via molecular dynamics simulations. Observations suggest a description of the dynamics in terms of st…

Emergence of Conduction Channels in Lithium Silicate
H. Lammert, A. Heuer
The existence of conduction channels in lithium silicate (Li_2O)(SiO_2) is investigated. Regions of the system where many different ions pass by form channels and are thus spatiall…
