Metal nanoparticles (MNPs) and semiconductor quantum dots (QDs) are two of the main building blocks of nano-scale systems with a wide range of applications in electronics and photonics. In view of the ubiquitous nature of the interparticle Coulombic decay process (ICD), which was also studied for paired QDs, we investigate ICD in the context of MNP-QD dimers. In this proposed scenario, the MNP is excited to a plasmonic state, which drives the emission of an QD electron. The energy transfer between the systems is mediated by the long-range Coulomb interaction. I will report on new developments towards a time-dependent description of the process, based upon the established electron dynamics methodology for paired QDs.
