摘 要: 采用皮秒量级的超快速光谱技术,分析了混晶GaAs1-xPx∶N材料发光瞬态过程.结果证实了材料随组份变化,从间接带到直接带(xc=0.45K,77K)转变的带增强效应. The pico second ultrafast spectroscopic technology is used to study the tenary GaAs 1-x P x∶ N alloys. The results confirm the band structure enhancement effect in GaAs 1-x P x∶ N alloys. The PL decay measurements of N X band show that the fast intraband tunneling and slow luminescent decay coexist in GaAs 1-x P x∶ N alloys.
