Altering the Fluorination Anodization Pathway of Silicon Near an Electrolyte Freezing Point Promotes the Formation of Blue-Photoluminescent Microstructures.

ABSTRACT: A fluoride-anion (F^-) governed electrochemical etching process, i.e., fluorination anodization, is used to construct unique silicon nanostructures owing to its reaction pathway, presenting a powerful and versatile strategy for fabricating advanced microsystems and quantum-based photonics devices. This fluorination anodization approach, which produces nanocrystals in anodized silicon, takes full advantage of the inherent crystalline quality of the prime wafers to achieve well-recognized photoluminescence via the quantum confinement effect. However, for heavily boron-doped (p⁺-type) silicon, fluorination anodization fails to produce a photoluminescent layer because the high doping level results in a coarse etching morphology. In contrast, performing anodiz
