摘要：

We report that gold thermally deposited onto n-layer graphenes interacts differently with these substrates depending oil the number layer, indicating the different surface properties of graphenes. This results ill thickness-dependent morphologies of gold oil n-layer graphenes, which can be Used to identify and distinguish graphenes with high throughput and spatial resolution. This technique may play ill important role ill checking if n-layer graphenes are mixed with different layer numbers of graphene with a smaller size, which cannot be found by Raman spectra. The possible mechanisms for these observations are discussed.
