Fig. 3From: Morphological Evolution of Pit-Patterned Si(001) Substrates Driven by Surface-Energy ReductionEvolution towards the equilibrium for a Si pit having an initial morphology as in Fig. 2b. a Perspective view showing the main morphological changes. b Top view of the morphologies in panel a. The time reported in panel b is expressed in arbitrary units. The color scale shows the values of \(\gamma (\hat {\mathbf {n}})\) at the surfaceBack to article page
