MedeA Application Notes for Glass & Ceramics

Reconstruction of a Silicon Carbide Surface The effect of strain on the reconstruction of a silicon-rich SiC(001) surface was computed using MedeA-VASP. The (3x2) reconstruction involves the formation and tilting of surface silicon dimers	Structure and Bond Lengths in Titanium Dioxide (TiO₂) In addition to the lattice parameters, the rutile structure has an additional degree of freedom, namely the position of the oxygen atom. This case study shows the simultaneous calculation of all these structural degrees of freedom.
Structure around Oxygen Vacancy in α-Quartz The introduction of vacancies in a crystalline solid causes a local rearrangement of atoms around the defect. The purpose of this case study is the prediction of such changes in α-quartz.
