✦ Synopsis

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 phenomenon, and discuss possible scenarios for experimental verification.

We present selective photoluminescence and photoluminescence excitation spectroscopy on self-assembled quantum dots. These spectroscopic techniques reveal a large apparent 'Stokes' shift in In(Ga)As-Ga(Al)As self-assembled quantum dots. We demonstrate that the first two excited states observed in PL
