Surface chemistry of porous silicon carbide, Journal of

The anodization reaction of SiC using HF solution makes a porous silicon carbide (PSC) layer develop. The luminescence behavior of PSC, however, is somewhat different from that of porous Si in that the so-called blue shift is not observed. Though the quantum confinement effect is said to be responsible for light emission in porous SiC, the surface state of PSC plays an important role. The
