For the surface with the larger roughness features, the receding meniscus has to dewet from fewer, but larger

• in the literature as the ‘surface topology model of stick-slip’ [23]. Based on this notion that ξ(x) is proportional to the surface roughness in MEMS, a measurement of the typical topology of the sidewall surface is required. We have made a special MEMS tribometer to do this, in which the counter

Topology of the layer is determined by the geometries of the connector and linker molecules, and typically a hexagonal pattern is formed due to the D3h symmetry of the connector moieties. Based
