Impact of 3nm Silicon Nanoparticles on Metal Si Schottky Junctions

Surface states in metal-Si interface play a big role in junction and interface physics. In this paper, we studied the impact of 3nm silicon nanoparticles (Si-NPs) at the metal-Si interface under dark and 1 sun conditions. We dispersed the Si-NPs on a clean p-type silicon wafer by drop casting. The nanoparticles formed a nano-layer coating on the Si substrate surface. The associated Schottky junction performance is assessed, and it is found to be different from non-NP's based junction. Moreover, a physical explanation for this behavior is presented and explained.
