Abstract:Frictional properties of two-dimensional structures on the nanoscale have gained importance, especially in the last decades, and a considerable amount of research is carried on to understand the interaction between their interfaces with well known lubricants. In industrial developments, these materials’ interfacial properties on metals have great importance. Therefore, in this thesis, we theoretically investigated the hexagonal BN and Au(111) interface with using molecular dynamics simulation. Calculation results have shown that the friction coefficient decreases with increasing load and a noticeable dependence on temperature is observed. We observed that the nanotribology properties of these two samples highly depend on sliding velocity, orientation and direction and also depend on the sizes, edges, and shapes of h-BN flake.
