| 摘 要： | 本文报道了在Zn0.76Cd0.24Se/ZnSe多量子阱(MQWs)中,用不同的Ar+激光线激发,观察到了共振增强的喇曼散射。首次在室温和77K的条件下,用Ar+的457.9nm谱线激发,观察到分别来自ZnSe垒层和Zn0.76Cd0.24Se阱层的限制纵光学声子模(LO)的喇曼散射,并对上述不同的光学模的起因进行了分析。

| Abstract: | Resonant Raman scattering from Zn0.76 Cd0.24 Se/ZnSe MQWs is presented under excitation of vaious lines of Ar+ laser. Very strong 2LO-phonon Raman scattering has been observed with Zn0.76Cd0.24Se well layers. It is ascribed to the strong outgoing resonant enhancement. For the first time, ZnSeWe-like LO phonon confined in ZnSe barrier layers and Zn0.76Cd0.24Se-like LO phonon confined in well layers are observed under the excitation of 457. 9nm line at room temperature and 77K, respectively. The origins of this two kinds of LO phonon are discussed. |
