Grain boundary triple junction dynamics: a continuum disconnection model
Chaozhen Wei, Luchan Zhang, Jian Han +2
The microstructure of polycrystalline materials consists of networks of grain boundaries (GBs) and triple junctions (TJs), along which three GBs meet. The evolution of such microst…
A Continuum Multi-Disconnection-Mode Model for Grain Boundary Migration
Chaozhen Wei, Spencer L. Thomas, Jian Han +2
We study the Grain Boundary (GB) migration based on the underlying disconnection structure and mechanism. Disconnections are line defects that lie solely within a GB and are charac…
Strong phonon localization in PbTe with dislocations and large deviation to Matthiessen's rule
Yandong Sun, Yanguang Zhou, Jian Han +5
Dislocations can greatly enhance the figure of merit of thermoelectric materials by prominently reducing thermal conductivity. However, the evolution of phonon modes with different…
