摘要：
The compatibility of gold with underlying substrate materials is important for device performance and reliability. Gold nanolayers of various thicknesses (4-14 nm) are deposited onto different substrates (glass and flexible substrate) by sputtering at room temperature. The flexible substrate used in the study was polyethylene napthalate (PEN). The structural and electrical properties of the Au thin films are compared between the two substrates. Contact angle measurements are done to understand the wettability of Au thin films on various substrates. The Au film on PEN showed hydrophobic behavior while the films on glass were distinctly hydrophilic with contact angle of around 50-68.5A degrees against water. The poor wettability is associated with increased roughness of the PEN substrate.
