Ultrafast dynamics of inorganic/organic hybrid nanostructures (B05)

项目B5旨在探索HIOS中低能激发的耦合机制和超快非平衡动力学，范围从5到几百meV。应用非线性时间分辨和相位分辨太赫兹光谱方法，研究了重掺杂ZnO上分子的等离子体-声子耦合激发以及掺杂半导体量子威尔斯阱中偶极分子与子带间激发的相互作用。这种混合激发有望产生新颖的线性和非线性光学性质，这在光电子学中的应用是有意义的。

Project B5 aims at exploring coupling mechanisms and ultrafast nonequilibrium dynamics of low-energy excitations in HIOS in the range from 5 to several hundreds of meV. Applying methods of nonlinear time- and phase-resolved terahertz spectroscopy, coupled plasmon-phonon excitations of molecules on heavily doped ZnO and interactions of dipolar molecules with intersubband excitations in doped semiconductor quantum wells will be studied. Such hybrid excitations are expected to result in novel linear and nonlinear optical properties which are of interest for applications in optoelectronics.
