Abstract

Near-field scaning optical microscopy (NSOM) revealed many important features of semiconductor nanostructures. As such, the unprecedented high spatial resolution of NSOM was achieved recently and a stikingly new feature in the single-dot spectroscopy was reported. The observation was interpreted in terms of a kind of the dead-layer model which gives a qualitative interpretation, a more quantitative theory that was necessary to estimate the ratio of the FWHM of the spatial extent of both luminescence pattens and to understand the quantum-dot-size dependence of that ratio.
