Highly uniform GaSb quantum dots with indirect-direct bandgap crossover at telecom range
Abhiroop Chellu, Joonas Hilska, Jussi-Pekka Penttinen +1
We demonstrate a new quantum-confined semiconductor material based on GaSb quantum dots (QDs) embedded in single-crystalline AlGaSb matrix by filling droplet-etched nanoholes. The…

Nanohole etching in AlGaSb with Ga droplets
Joonas Hilska, Abhiroop Chellu, Teemu Hakkarainen
We demonstrate nanohole formation in AlGaSb by Ga droplet etching within a temperature range from 270°C to 500°C, allowing a wide range of tunability of the nanohole density. By le…
