Abstract
An analysis of the influence of confined acoustic phonons on the pure dephasing of a single quantum dot located in a half space or a free-standing slab is given. We find that the proximity to a surface leaves distinct traces in the polarization and the absorption spectrum which can be traced back to the interaction of the dot with surface phonons and a reflected phonon wave packet.
