Incorporating point defect generation due to jog formation into the vector density-based continuum dislocation dynamics approach
Peng Lin, Vignesh Vivekanandan, Benjamin Anglin +2
During plastic deformation of crystalline materials, point defects such as vacancies and interstitials are generated by jogs on moving dislocations. A detailed model for jog format…
On the computational solution of vector-density based continuum dislocation dynamics models: a comparison of two plastic distortion and stress update algorithms
Peng Lin, Vignesh Vivekanandan, Kyle Starkey +3
Continuum dislocation dynamics models of mesoscale plasticity consist of dislocation transport-reaction equations coupled with crystal mechanics equations. The coupling between the…
Accurate first principles detailed balance determination of Auger recombination and impact ionization rates in semiconductors
S. Picozzi, R. Asahi, C. B. Geller +1
The technologically important problem of predicting Auger recombination lifetimes in semiconductors is addressed by means of a fully first--principles formalism. The calculations e…
Impact ionization in GaAs: a screened exchange density functional approach
S. Picozzi, R. Asahi, C. B. Geller +2
Results are presented of a fully ab-initio calculation of impact ionization rates in GaAs within the density functional theory framework, using a screened-exchange formalism and th…
