Fig. 2From: Surrogate model for optimizing annealing duration of self-assembled membrane-cavity structuresTwo-dimensional axisymmetric model of the reference case (\(r_{hole}=0.5\) \(\upmu\)m, \(\text {AR}=3\), and \(S=0.35\) \(\upmu\)m); a geometry and mesh. b shape evolution of a single hole until the cavity becomes sphere. Simulation time of 200 s is considered as reference time (\(t_r\)) for parametric studyBack to article page
