摘要: Polarization characteristics of luminescence from partial dislocations (PDs) in 4H-SiC have been investigated by room-temperature photoluminescence (PL) imaging. After expansion Shockley stacking faults high-power laser irradiation, PL PDs tilted 6° their Burgers vector (6°-PDs) was observed with almost the same peak energy as that 30°-Si (g) PDs. The and 6°-PDs which were mobile under illumination both found to be polarized perpendicular dislocation lines. In contrast, immobile 30°-C(g) not polarized. present results suggest carriers bound anisotropic wave functions those 30°-C(g)PDs isotropic functions.
