Droplet etching of deep nanoholes for filling with self-aligned complex quantum structures [PDF]
Nanoscale Research Letters, 2016 Strain-free epitaxial quantum dots (QDs) are fabricated by a combination of Al local droplet etching (LDE) of nanoholes in AlGaAs surfaces and subsequent hole filling with GaAs. The whole process is performed in a conventional molecular beam epitaxy (MBE)

Telecom O-Band Quantum Dots Fabricated by Droplet Etching
CrystalsWe 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.

Local droplet etching on InAlAs/InP surfaces with InAl droplets
AIP Advances, 2022 GaAs quantum dots (QDs) grown by local droplet etching (LDE) have been studied extensively in recent years. The LDE method allows for high crystallinity, as well as precise control of the density, morphology, and size of QDs.
