摘要：
The confined logitudinal-optical (LO) phonon and surface-optical (SO) phonon modes of a free-standing cylindrical quantum dot are discussed within the dielectric continuum approximation. It is found that there exist two types of SO phonon modes: top SO (TSO) mode and side SO (SSO) in a cylindrical quantum dot. The operators describing the free phonon modes and their interactions with electrons in the system are also derived.
