Effects of Thermal Annealing and Selective Chemical Etching on Structural and Optical Properties of GaAsBi Epilayer with Droplet Systems.

Journal of Nanoscience and Nanotechnology, 2019
A GaAs1-xBix layer was grown by molecular beam epitaxy (MBE) with a low Bi content (2.3%) on GaAs maintaining the substrate at a non-rotating state and was then annealed at 750 °C, 800 °C and 850 °C.

Direct Etch Method for Microfluidic Channel and Nano-Height Post Fabrication by Picoliter Droplets

19th IEEE International Conference on Micro Electro Mechanical Systems, 2006
Photolithography is an expensive and significant step in microfabrication. Approaches that could change lithography would create an impact on semiconductor industry and microelectromechanical systems technologies. We demonstrate a direct etching method by ejecting etchant droplets at desired locations by using microdroplet ejector arrays.

Local droplet etching – Nanoholes, quantum dots, and air-gap heterostructures

AIP Conference Proceedings, 2014
Local droplet etching (LDE) allows the self-organized generation of nanoholes in semiconductor surfaces and is fully compatible with molecular beam epitaxy (MBE). The influence of the process parameters as well as of droplet and substrate materials on the LDE nanohole morphology is discussed.

Droplet etched GaAs quantum dots close to surfaces and metallic interfaces

Journal of Applied Physics, 2017
GaAs quantum dots (QDs) with a thin cap layer are studied as building blocks for self-aligned hybrids with a metallic nanostructure (MN). Both constituents are filled into a nanohole template that is drilled into an AlGaAs surface by self-assembled local droplet etching during molecular beam epitaxy.

Nanoengineered Surfaces for Robust Droplet TENGs: Mitigating Contamination and Improving Longevity

Advanced Functional Materials
The droplet triboelectric nanogenerator (D‐TENG) harnesses energy from natural water droplets, though its performance and lifespan can be compromised by contamination on the functional layer.
