Nettet4. okt. 2006 · For example, when we are discussing ionic crystals, it is essential that we review the Mott-Littleton method, and the original paper by these authors appeared in 1938. The real upsurge in interest in the type of calculation we are reviewing largely parallels the development of modern electronic computers. Nettet5. des. 2007 · For these calculations we used the Mott-Littleton method to calculate the defect formation energies. This method is based on dividing the crystal into two regions (I and II), and describing each with a different level of approximation (Catlow, 1989).

"Nettet2.6.1 Mott-Littleton Methodology. In the Mott-Littleton methodology [274] the defect energy is calculated by splitting the system into two regions; in the first region the ions are fully and explicitly affected by the defect, which sits at the centre of the region, whereas for region 2, which extends to infinity, only the displacements of the ...

NettetDefect formation energy is evaluated by Newton-Raphson energy minimization with Mott-Littleton method[8]. 2-2-1. Energy minimization. Equilibrium structure is found by searching the minimum of the potential surface. The true minimum, global minimum can be searched via either the Monte Carlo, simulated annealing or genetic algorithms.
