Figure 2From: Fabrication of porous silicon by metal-assisted etching using highly ordered gold nanoparticle arraysCharacterization of highly ordered gold nanoparticle arrays. Gold nanoparticles were deposited onto silicon which has been cleaned with piranha solution. (A) SEM image of a highly ordered gold nanoparticle array. The diameter of the gold nanoparticles was 55 ± 9 nm and the interparticle distance was 111 ± 13 nm. (B) Corresponding pair distribution function.Back to article page
