The resulting reduction of the band gap can be up to 250 meV (Figure 2a), more than 20% of the bulk value of the band gap for the thinnest ribbons. It is possible to conﬁrm this band gap modulation experimentally, at least qualitatively. In separate stud-ies on

Porous silicon (PSi) exhibits several notable attributes including direct and wide modulated energy band gap, high resistance, large surface-to-volume ratio, and identical single-crystalline structure as bulk Si. These properties are beneficial for making9, 10].
Silicon carbide (SiC) is a wide-band-gap semiconductor with excellent chemical stability, electronic properties, high rigidity, and high hardness . Considering that the macroscopic properties mainly depend on the SiC microstructure, a clear picture of atom packing during formation processes is important.

Silicon carbide is superior to silicon in some appliions as it has higher thermal conductivity, a wider band gap, is thermally and chemically inert, and features a higher breakdown field. These characteristics make it appealing for use in transistors (JFETS, MOSFETs, etc.), for appliions like high temperature electronics, as well as in rapid high voltage devices for more effective power
