Interface phonons in CdSe/Zns core/shell-nanorods — •Holger Lange1, Maria Machon1, Mikhail Artemyev2, Ulrike Woggon3, and Christian Thomsen1 — 1Institut für Festkörperphysik, Technische Universität Berlin — 2Fachbereich Physik, Universität Dortmund — 3Institute for Physico-Chemical Problems of Bellorusian State University, Minsk
We discuss surface optical phonon modes and interface optical phonons in plain CdSe nanorods of different sizes and CdSe nanorods with an epitaxial grown ZnS shell. The related Raman bands are not only influenced by the geometry of the nanorod, but also by the presence and structure of the shell.
