Abstract

We investigated the resistance properties of thin film gold deposited on a 3D-printed cantilever using a sputter coater. We used current-voltage (IV) curves to measure the resistance of the film as a function of thickness. The results exhibited classic behavior in thicker films and quantum behavior in thinner films. Additionally, we analyzed the change in resistance as the cantilever was flexed. A linear relationship was found between the resistance of the gold film and the displacement of the cantilever. Only the 8 nm film deviated from the trend, showing erratic behavior when bent downward.
