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.
