Single photon emission and recombination dynamics in self-assembled GaN/AlN quantum dots
Johann Stachurski, Sebastian Tamariz, Gordon Callsen +2
III-nitride quantum dots (QDs) are a promising system actively studied for their ability to maintain single photon emission up to room temperature. Here, we report on the evolution…

Towards bright and pure single photon emitters at 300 K based on GaN quantum dots on silicon
Sebastian Tamariz, Gordon Callsen, Johann Stachurski +3
Quantum dots (QDs) based on III-nitride semiconductors are promising for single photon emission at non-cryogenic temperatures due to their large exciton binding energies. Here, we…

Probing alloy formation using different excitonic species: The particular case of InGaN
Gordon Callsen, Raphaël Butté, Nicolas Grandjean
Since the early 1960s, alloys are commonly grouped into two classes, featuring bound states in the bandgap (I) or additional, non-discrete band states (II). Microscopic material pa…
