The Influence of Preparation Parameters on Structural and Optical Properties of n-Type Porous Silicon
The interest in macroporous silicon has increased greatly over the two last decades mainly due to its several potential applications as capacitors , membrane (pump of particles) , solar cell , Metallic barcodes . etc. Macroporous silicon (MPS) can be fabricated with straight pores and smooth pore walls by using back side illumination of n-type Si which is widely used in macropore formation on n-type silicon (n-Si) by photoelectrochemical anodization in aqueous HF containing electrolytes. Anodic oxidation of silicon is connected with the consumption  of holes at the surface.
