Fig. 4From: Morphological Evolution of Pit-Patterned Si(001) Substrates Driven by Surface-Energy ReductionEnergy decreasing during the evolution of pit geometries. a F(t) normalized by the energy of the flat (001) surface obtained as final stage of the evolution. Energy decays obtained from the simulations having different R for the initial profile, namely, from R = 0.1 to R = 0.75, are shown. Time is expressed in arbitrary units. b Curves as in panel a shifted in order to match \(t_{R}^{*}\), i.e., the time at which the global flattening of the pit is achieved depending on R Back to article page
