Abstract
In this work, a method based on simple geometrical considerations is proposed for a more accurate measurement of the quantum dots (QDs) diameter. For this purpose actual QD dimensions from atomic force microscope images and the radius of the probe tip are only necessary. The method is used to characterize self-assembled InAs/GaAs QDs prepared by molecular beam epitaxy (MBE), which exhibited a bimodal size distribution. Accepting the approximate spherical canopy QD shape and the similar coefficient of the relationship p = r/h for two groups of QDs with different sizes, one obtains the value of the tip radius and diameters of the QDs in the plane of nucleaction.
