Space charge behavior of quantum dots filled polymeric resin matrices

In this article the incorporation of core CdSe and coreshell CdSe-ZnS Quantum Dots in an epoxy resin is studied. In particular, TSDC and PEA measurements were performed in order to understand whether the nanofillers had an impact on the electrical behavior of the resin. The results show that Quantum Dots influence space charge behavior, introducing traps which are significantly deeper than the pure resin ones. Moreover, space charge injection phenomena seem to be reduced by the presence of nanoadditives.
