摘要
We report a simple single-step etching method for formation of black surface on silicon wafer by using HAuCl4-HF-H2O2 etching solution, in which catalytic Au particles were deposited in situ. The black surface suppresses the reflectivity in a wide spectral region. The formation mechanism involved has been discussed.
