5/10/2020, · Calculation Details. DFT was used to simulate the dissolution of a metal ion from the metal surface as follows. A four-layered p (3x3) (111) surface slab was created, and the height of the periodic supercell is 3 nm with vacuum on top of the surface to minimize interactions with slab images.

The calculations need to be done in two steps. The first step is a standard DFT or hybrid functional calculation, where the number of bands is increased to include the relevant conduction bands in the calculation: System = Si NBANDS = 16 ! or any larger desired value ISMEAR = 0 ; SIGMA = 0.05 ALGO = D !
