Key Points

The aim is to explore the control of GaAs quantum dots through local droplet etching with minimal material.
Utilized atomic force microscopy to analyze dot properties.
Conducted Voronoi analyses to assess the growth dynamics and arrangements of the dots.
Developed a cost-effective micro-photoluminescence setup using components from Blu-ray players.
Demonstrated a linear relationship between hole density and arsenic pressure.
Confirmed high-quality quantum dots with hexagonal arrangements.
Indicated the formation of quantum rings around the dots from initial measurements.

Implication

Investigation of GaAs quantum dots' properties through photoluminescence analysis and etching methods, indicating structural quality.
