增氮效应
6) nitrogen-doped effect
掺氮效应
1.
The longitudinal optical phonon-plasmon coupled modes (LOPC modes) of different SiC polytypes show that the nitrogen-doped effect of 6H-SiC is markedly different from that of 4H-SiC, and is similar to that of 15R-SiC under the growth condition of nitrogen-doped 6H-SiC single crystal.
不同SiC多型体的纵光学声子与等离子体激元的耦合模 (LOPC模 )表明 :在掺氮 6H SiC单晶的生长条件下 ,6H SiC的掺氮效应与 4H SiC存在明显差别 ,而与 1 5R SiC的掺氮效应相
