The optically induced polarization fatigue in SBTN films is due to trapping of photo-generated charge carriers at domain boundaries.
这种光诱导剩余极化减小的疲劳,主要机理是光生载流子电畴钉扎。
The results show that the steady-state photo-generated potential outside the light illumination range presents linear distribution and the information detected by PSD is the energy center of spot.
