Gold-enhanced mechanical exfoliation method attracts broad interests inrecent years, which has been widely used for preparing large-area andhigh-quality 2D single crystals. Even many calculations predict that thereis strong interaction between Au film and the exfoliated 2D crystals, directexperimental evidence is still lacking. Here, we perform Raman spectroscopymeasurements for few layer MoS$_{2}$ with and without Au film underneath.The main peaks of MoS$_{2}$ on Au film show no obvious change at higherfrequency, however, the breathing and shear modes at low-frequency aresuppressed, especially for breathing modes. In contrast, both breathingmodes and shear modes can be detected on suspended MoS$_{2}$ and the samples aretransferred from Au film to SiO$_{2}$/Si. These comparison results providedirect evidence for the existence of covalent-like quasi-bonding at theinterface of Au film and the exfoliated MoS$_{2}$ crystal. This MoS$_{2}$/Auinterface interaction presents a special pinning-effect for low-frequencyrigid vibration. Similar pinning-effect is also discovered in WS$_{2}$/Ausystem. Our work reports the suppression of low-frequency Raman modes ofMoS$_{2}$, WS$_{2}$ on Au film, which will deliver new inspiration forstudying other interactions between layered materials and solid surfaces.
