Fabrication of superhydrophobic aluminum surface by droplet etching and chemical modification

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2019
The development of techniques to fabricate superhydrophobic aluminum surfaces is rapidly maturing, yet the problems of high loss of material and complex preparation still persist.

Droplet etching with indium – Intermixing and lattice mismatch

Journal of Crystal Growth, 2019
In contrast to Indium droplets the usage of Ga or Al droplets for the local droplet etching (LDE) technique is well established. It has been shown previously that In-droplets or In-alloys can be used for LDE with focus on small hole-depths at low etching

On the mechanism of the micro-droplet etching of silicon wafers for texturization

Materials Science in Semiconductor Processing, 2019
Polished silicon wafers were used for the present study to remove the effect from surface mechanical damages. It was shown that conventional HF-HNO3-H2O bath wet etching cannot generate any texture on the polished silicon, while the micro-droplet etching

Alloying during local droplet etching of AlGaAs surfaces with aluminium

Journal of Applied Physics, 2019
Local droplet etching (LDE) drills self-assembled nanoholes into AlGaAs surfaces and represents a powerful technique for the fabrication of versatile quantum structures like quantum dots, rings, and molecules. Usually, LDE is performed at temperatures T =

Self-Assembly of Semiconductor Quantum Rings by Local Droplet Etching

Journal of Nanoelectronics and Optoelectronics, 2011
We give an overview on the self-assembly and optical properties of strain-free semiconductor quantum rings (QRs) generated by the novel technique local droplet etching (LDE). LDE is fully compatible with conventional molecular beam epitaxy equipment and utilizes liquid metallic droplets which perform a spatially limited drilling and form nanovolcanoes ...

Density limits of high temperature and multiple local droplet etching on AlAs

Journal of Crystal Growth, 2014
Abstract The density of nanoholes created by self-assembled Al droplet etching of AlAs surfaces during molecular beam epitaxy is studied. We find a clear decrease of the hole density with increasing etching temperature T up to a threshold temperature T = 620 ° C . At T > 620 ° C , the hole density saturates at a minimum of 2 ×

Study on the asymmetry of nanopore in Al droplet etching

Optical and Quantum Electronics, 2021
In the local droplet etching (LDE) method, the fine split structure (FSS) of quantum dots (QDs) is directly related to the shape of the nanopores formed after annealing. The formation of highly symmetrical nanoporous is the key to the preparation of GaAs/AlGaAs QDs with small FSS.
