Wet etching of GaN, AlN, and SiC: a review - ScienceDirect
2005/1/17· The silicon face remained smooth except for etch pits while the carbon face became roughened during etching. The same rule applies to α-SiC and 15R SiC as well  ,  ,  ,  in that silicon face was not significantly attacked, while the carbon face changes from smooth to a needle like structure, and then to a “wormy” appearance as the etching temperature increases  .
