✦ Synopsis

We have used Deep Level Transient Spectroscopy to investigate self-organized InAs/GaAs quantum dots. The existence of different dot families is confirmed by the deconvolution of the spectra in Gaussian components with full width at half maximum of 60-70 meV. The strain of quantum dots is responsible for the relaxation of large quantum dots leading to generation of dislocations.

An array of elongated quantum dots (quantum dashes) can self polarize into an antiferroelectric state. In contrast to the conventional antiferroelectricity, this spontaneous polarization does not require any ionic displacements for its establishment. We present the main arguments and proofs of this
