Due to the cation and anion surface reconstruction properties, one Cd-Se atomic layer epitaxy (ALE) cycle produces a coverage of 0.5 CdSe monolayers. In this work we demonstrate that even when an odd number of cycles are deposited to produce ultra-thin quantum wells, under the appropriate growth conditions, the photoluminescence spectrum indicates the absence of thickness fluctuations. A single excitonic peak is detected in the whole sample.
