Cover Story: The method of the adhered cantilever, borrowed from microtechnology, helps us to gain fundamental knowledge about Casimir–Lifshitz forces acting at distances of about 10 nm, which are difficult to access in Casimir-type experiments. A recently presented setup measures the shape of cantilevers with high precision needed for the analyses of the involved forces. Several nonidealities crucial for the data analysis are revealed. We deduce a generalized formula including these nonidealities to the adhesion energy. The application of the formula is demonstrated using the first test result from the setup. The roughness of interacting surfaces, which deviates significantly from the normal distribution, plays an important role. The method is demonstrated to be suitable for the determination of Casimir–Lifshitz forces at short separations. View this paper
