Abstract
Three-dimensional confinement of excitons or electrons motion in nanometer-sized microcrystallites (nanocrystals – NCs) is an important phenomenon in physics, and is expected to bring a significant improvement to ultrafast functional devices. In the past ten years, several types of quasi-zero-dimensional (QZD) media such as dielectric matrices containing dispersed semiconductor or metal NCs have been realized by using various techniques. Recently, we have succeeded in the preparation of thin-film QZD media [1]. Such media are very suitable for investigating the effect of the microstructure (including the average size, the concentration, the arranging types of NCs and the matrix material) on the quantum confinement of the electron-hole motion.
