WebA finite element model of the cantilever beam is implemented to include a non-uniform thickness along its length, due to focused ion beam trimming. A quasi-static, iterative approach is used to calculate the cantilever profile for a given bias voltage. Two focused ion beam trimming strategies are compared. Web22 hours ago · Focused ion beam (FIB) milling is a mask-free lithography technique that allows the precise shaping of 3D materials on the micron and sub-micron scale. The recent discovery of electronic nematicity in La2−xSrxCuO4 (LSCO) thin films triggered the search for the same phenomenon in bulk LSCO crystals. With this motivation, we have …
