In 1956 porous silicon was first discovered. The material gained importance in the 1990s when two optical properties were discovered. In the study of transmembrane proteins, a porous silicon membrane of 3 micrometers diameter was produced, which produced a high-resolution image of the surface of a single protein.
Electrochemical Impedance Spectroscopy (EIS) investigated the protein and the experiment was published in the Journal of The American Chemical Society (ACS) journal ACS Nano in June 2014.
The experimental process required the development of a porous silicon membrane, followed by the synthesis of an epithelial sodium channel protein (ENaC) in Langmuir - Blodgett - Lang Muir and Schafer technique. Finally, the epithelium - sodium - channel - protein EN aC was fused to form a lipid two-layer membrane.
The functioning of the device was investigated by means of electrochemical impedance spectroscopy (EIS) and magnetic resonance imaging (MRA).

Porous silicon is a semiconductor that is made from a single crystal of silicon. Its pore size and structure are important for different applications. This material can be used in electronics because of its high surface area. In addition to this, porous silicon can serve as a precursor to thick oxide layers on Si and can serve as a dielectric layer for capacitance-based chemical sensors. In the 1980s, two independent research groups found that a crystalline thin film of porous Si can exhibit quantum confinement effects, which allow for the study of electrons.
Porous silicon is a mesoporous material that has found many uses in biomedical devices.

Porous silicon is biocompatible and has been used in optoelectronics for flowering and for the study of transmembrane proteins. It can be used for solar cells where a thin layer of porous silicon is required. Porous silicon formation is supported by gold, and the holes necessary for the removal of silicon atoms are created by the reduction of hydrogen peroxide with gold as the metal catalyst. The desired pattern of the porous area is achieved because porous silicon formation only occurs in the area coated with the metal catalysts. [Sources: 1, 2]
If the energy of a photon is greater than the band gap of the silicon, it is absorbed and removed. If the light generated by the holes is facilitated by an energy in the photon lower than that of its absorption by silicon (e.g. 0.1%), the photons are absorbed and light is not absorbed due to the presence of silicon atoms. By annealing at high temperatures for a long enough time, the transport of silicon atoms over long distances causes their neighboring regions to fill with pores in a sponge-like structure - similar to a structure (i.e., voids diffuse at the surface). In order not to recombine with the free electrons in silicon wafers, holes are injected into silicon atoms, which then turn out to be local anodes and oxidize (as shown in Eq). [Sources: 0, 2]
The last porous silicon layer serves as the device layer, forming the first porous layer of the silicon substrate. Oswald's maturation process reorganizes many of these pores into large cavities, creating a brittle structure that is more resistant to oxidation than previous porous layers of silicon wafers.

The porosity and thickness of the porous silicon is determined during the anodisation process, and the silicon coating, which can determine the duration of silane exposure, is crucial for the formation of porous silicon. The formation and SiOxFy of this layer stabilizes the final porous structure, which is increasingly resistant to oxidation than the pores in the silicon substrate and therefore more suitable for the formation of the RF-based silicon structure of silicon wafers than any other porous silicon structure formed by HF.

In 1999 Bessais and his colleagues observed that porous silicon can be produced in a device sprayed with RF droplets, but the etching rate was only a few nanometers per hour . The resolution of the silicon wafer is possible in RF-based solutions that are created by holes in the silicon surface. It is assumed that during the hydrogenation step, the radical hydrogen plasma replaces the dangling bonds in an amorphous silicon layer with hydrogen radicals from the plasma. The H2 is then exhausted during annealing in this specimen, and a local melt leads to a depassivating silicon surface and the formation of a porous silicon layer. [Sources: 2]
The reduction of porous silicon is the bottom line - right down to the synthesis of porous silicon structures. N - type silicon substrates, In this method, the formation of a porous structure is limited to the N-silicon substrate, as the solution contains a silicon interface that exists in the electric field on the silicon. The holes are pressed into the surface, where they can facilitate the removal of nearby silicon atoms, while the electric fields of the building drive away the holes. [Sources: 2]
The bottom-up approach to the realization of porous silicon is to collect a laser - derived silicon clusters. Since external potentials are not applied to the silicon wafer while being etched into the path, the resolution of silicon atoms has a localized electrochemical mechanism. It is known that large currents flow through the surface of a silicon substrate and react with the pore walls, which means that the bottom of the silicon substrate is anodised to form a porous layer with a surface of about 1.5 micrometers. If an electric current is passed through a silicon wafer, a critical current density (J / PSL) is achieved, which is exceeded by a large number of pores or pores in the upper and lower layer of an N silicon substrate.
