Abstract :
We present an impression of the present state of knowledge on the formation, via a modified Stransky-Krastanov growth mode, of InAs quantum dots (QD) on GaAs substrates. In order to fulfil this requirement, we have grown by MBE a single sample with gradient coverage and its analyses being performed by means of atomic force microscopy.
