A conductivity-selective photoelectrochemical etching process was reported to fabriion single-crystal SiC micro/nanoelectromechanical structures. When a bias employing the different flatband potentials of n-type and p-type SiC in the KOH solution was applied, p-SiC suspended micro and nanostructures were released by undercutting the underlying n-SiC substrate. The etching of n-SiC was
