Black GaAs by Metal-Assisted Chemical Etching [PDF]
ACS 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 ...
