Plasmonic properties exhibited by some metallic particles at different wavelengths are being exploited. Metallic nanoparticles such as gold (Au), silver (Ag), and copper (Cu) exhibit surface plasmon resonance (SPR) at broad wavelengths (400-800 nm). Furthermore, metallic nanoclusters such as Ag, Au, and Cu, which exhibit SPR at wavelengths of 450 nm, 520 nm, and 650 nm, are used in photodevice construction. Today, metallic materials are produced as thin films using various methods (chemical and vacuum evaporation). These methods are called thermal methods, and the resulting crystal structure consists of clusters of different sizes. For an effective SPR event, metallic nanoparticles should have uniform nano sizes. In this study, Au layers were deposited in clusters of equal size on a cooled n-Si surface using cryogenic techniques at different substrate temperatures (300 K-100 K) to fabricate AuNp/n-Si/Al optoelectronic devices. Among the devices fabricated under different regimes, the best performance was achieved with the Au layer fabricated at 230 K substrate temperature.
