Facet Formation

We perform the first-principles calculations on the 4H-SiC(0001) surface and clarify the mechanism of the facet formation. We first identify atomic structures of single-, double- and quadribilayer steps and find that the single-bilayer (SB) step has the lowest total energy among these three step structures. Then, we reveal that the nanofacet consisting of SB steps is more energetically stable than the equally spaced SB step and the surface-energy variation caused by the difference of stacking sequences of the bi-atomic layer near the surface is an important factor of the facet formation.

First Principles Study

First principles density functional calculations have been performed for a number of Al(100) twisted interfaces with the purpose to investigate the most stable atomic structures. Orientation dependence of interface energy normalized to bulk is established and discussed. The obtained results can be used to model grain growth in molecular dynamics studies.
