Gold Sputtering Target

Goodfellow's Gold Sputtering Target, made from high-purity gold, supports advanced research into nanoscale materials by enabling the deposition of uniform gold layers on substrates. These layers are essential for examining the unique electrical and optical properties of gold at small scales, providing insights into phenomena like quantum effects and surface interactions. Such characteristics make these gold nanolayers valuable for applications in sensors, photonic devices, and precision engineering, advancing research in sectors like aerospace, biomedical technology, and energy solutions.
