Evolution of InAs nanostructures grown by droplet epitaxy [PDF]

Applied Physics Letters, 2007
The authors report the growth evolution of InAs dot and ring nanostructures with the indium deposition amount on GaAs (001) by droplet molecular beam epitaxy. There is a critical flux for the indium to form InAs dots even when there is no droplet.

Droplet Epitaxy Quantum Ring Structures

Journal of Nanoelectronics and Optoelectronics, 2011
The Droplet Epitaxy allows for the design and the realization of extremely complex semiconductor quantum ring structures, which range from single ring, multiple concentric quantum rings and coupled ring/disk structures. The fabrication and the characterization of such quantum ring complexes is here reviewed.

Origin of Quantum Ring Formation During Droplet Epitaxy [PDF]

Physical Review Letters, 2013
Droplet epitaxy of GaAs is studied in real time using in situ surface electron microscopy. The resulting movies motivate a theoretical model for quantum ring formation which can explain the origin of nanoscale features such as double rings observed under a variety of experimental conditions. Inner rings correspond to GaAs deposition at the droplet edge,

The structural symmetry of nanoholes upon droplet epitaxy

Nanotechnology, 2021
Abstract Nanoholes obtained by droplet epitaxy has been intensively investigated as an important material platform for the fabrication of nanodevices due to their unique topology. However, the final fabricated nanoholes are very difficult to achieve a highly symmetric circular structure, and usually have two or four gaps in the ...
