There is an increasing interest in the properties of nanostructures, in which the carrier motion is confined in all three dimensions, as in self-assembled quantum dots and nanocrystallite quantum dots [1]. The reason for this interest lies, for example, in the properies of the 0D (zero-dimensional) structures, which promise efficient low-treshhold current lasers for optoelectronic applications. One of the practical problems in this respect is the question of the rapidity of the relaxation of the excited electronic subsystem and thequestion of the width of the optical line. It is the aim of theoretical and experimental studies to answer the question of which properties of 0D objects are inherent properties of these structures, and which are determined or influenced by the technological process.
