Wetting layer in metamorphic quantum dots
Why is it important?
This study evidences that wetting layer states are absent in metamorphic InAs/InGaAs structures. This a result of great interest as these structures are strong candidates for the development of single photon sources in the 1.3 - 1.55 µm range
