(a) Microscope image of the Al_0.98Ga_0.02As layer after oxidation process. The color difference was caused by the large refractive index difference between the oxide and the original Al_0.98Ga_0.02As layer. (b), (c) The surfaces of the devices with and without AgNW film, respectively. The surface was smooth and clean before applying the AgNW film.
