Abstract

Optical spectroscopy in one-dimensional (ID) and zero-dimensional (OD) semiconductor structures has been applied in recent years to investigate the peaked density of states.1-4 However, inhomogeneous broadening of the photoluminescence (PL) line caused by fluctuations in composition and structure size within arrays of ID and 0D systems made a clear identification of lateral quantization difficult. This inhomogeneous broadening is eliminated in spectroscopy of a single OD system.
