The CDFT (which is a first-order Born approximation theory) was used in many studies, starting from the pioneering works [10], [11], which calculated the interaction cross section of charged particles with the electronic subsystem of the solid, and continuing with MC codes for practical cases like track structure and SEU in silicon devices [19].

We have used the CDFT formalism to study possible metastable frustrated magnetic states of a V 4+ kagome slab by comparison of the total SC energy between different states. The kagome lattice is a two-dimensional network of corner-sharing triangles that is known to host exotic quantum magnetic states [ 30 ].
