Revisiting the theory of crystal polarization: The downside of employing the periodic boundary conditions
Qiu-Shi Huang, Su-Huai Wei
Periodic boundary condition (PBC) is a standard approximation for calculating crystalline materials properties. However, a PBC crystal is not the same as the real macroscopic cryst…

Mechanism of Defect Generation in Ionizing-irradiated -SiO: The Nonradiative Carrier Capture-Structural Relaxation Model
Yu Song, Chen Qiu, Su-Huai Wei
The total ionizing dose (TID) effect of semiconductor devices stems from radiation-induced defects in the -SiO dielectrics, but the conventional ``hole transport-trap…
