Black GaAs by Metal-Assisted Chemical Etching [PDF]

open access: yesACS Applied Materials & Interfaces, 2018
Large area surface microstructuring is commonly employed to suppress light reflection and enhance light absorption in silicon photovoltaic devices, photodetectors, and image sensors. To date, however, there are no simple means to control the surface roughness of III-V semiconductors by chemical processes similar to the metal-assisted chemical etching ...

Schottky Barrier Catalysis Mechanism in Metal-Assisted Chemical Etching of Silicon

open access: yesACS Applied Materials & Interfaces, 2016
Metal-assisted chemical etching (MACE) is a versatile anisotropic etch for silicon although its mechanism is not well understood. Here we propose that the Schottky junction formed between metal and silicon plays an essential role on the distribution of holes in silicon injected from hydrogen peroxide.
