Droplet epitaxy was proposed to fabricate quantum dots in the early 1990s. Even though
many research efforts have been devoted to droplet epitaxy since then, it is only until …

Normal incident photodetection at mid infrared spectral region is achieved using the
intersublevel transitions from strain-free GaAs quantum dot pairs in Al0. 3Ga0. 7As matrix …

We report on the ability to fabricate super low density InGaAs semiconductor ring-shaped
nanocrystals on a GaAs (100) surface by molecular beam epitaxy. Specifically, we …

We investigate the effect of annealing temperature on self-assembled Au droplets on Si
(111). The annealing temperature is systematically varied while fixing other growth …

We report the fabrication of extremely high-density GaAs quantum dots (QDs) by droplet
epitaxy. We investigated the dependence of temperature and coverage on the dot density …

We present a study on the formation of In droplets on GaAs (100) substrates as functions of
substrate temperature and monolayer (ML) deposition by using molecular beam epitaxy …

We have demonstrated photopumped laser action of self-assembled Ga As∕ Al Ga As
quantum dots (QDs) grown on GaAs (311) A substrate by droplet epitaxy. Due to the short …

Formation processes of Ga droplets on polar (111) A and (111) B surfaces of GaAs have
been investigated. A single Ga atom forms a stable nucleus on the (111) A surface, so that …

We demonstrate a number of unseen self-assembled nanostructure complexes fabricated
on various GaAs surface indexes by droplet epitaxy. Even under identical growth conditions …

Au nano-clusters and nanoparticles (NPs) have been widely utilized in various electronic,
optoelectronic, and bio-medical applications due to their great potentials. The size, density …
