SEM images of various morphologies of Ag nanoparticles on tSi at different stages of the processing: a chains of nanoparticles self-assembled in the inter-pyramid valleys, b NNN after sintering by RTP, c BNNN, d large magnification image of BNNN, e large magnification image of BNNN after removal of NP, showing the etching pits, and f XRD pattern of BNNN on tSi as compared to that for the bare silicon wafer. The scale bars in a–c are 10 μm and in d and e are 1 μm
