通过利用外延剥离，ZnCdSe 量子阱被转移到 LiNbO3 基板上，以利用其增强的压电特性。表征了这种混合结构的光致发光发射，并研究了表面声波对自由激子和束缚激子发射的影响。最后，发射两个反向传播的表面声波，导致声波介导的激子解离减少。
By making use of epitaxial lift-off, ZnCdSe quantum wells are transferred onto a LiNbO3 substrate in order to employ its enhanced piezoelectric properties. The photoluminescence emission of this hybrid structure is characterized and the influence of a surface acoustic wave on the free exciton and bound exciton emission is investigated. Finally, two counterpropagating surface acoustic waves are launched leading to a decrease in the acoustic wave mediated exciton dissociation.
