Abstract

Semiconductor quantum dots (QDs) provide excellent ground to explore many fundamental physical phenomena. One of such phenomena is quantum coherence/decoherence of confined carriers which is critical for quantum information processing and other applications. Recently, such phenomena have been studied experimentally¹ as well as theoretically² in naturally formed quantum dot systems. On the other hand, for technologically more important self assembled quantum dots (SAQDs), various experimental³ and theoretical⁴ investigations indicate a much richer electronic structure and more complex inter-level energy relaxation mechanisms.
