Telecom O-Band Quantum Dots Fabricated by Droplet Etching

open access: yesCrystals
We present a novel growth technique for fabricating low-density InAs/GaAs quantum dots that emit in the telecom O-band. This method combines local droplet etching on GaAs surfaces using gallium with Stranski–Krastanov growth initiated by InAs deposition.
