The significance of CDFT is necessarily ephemeral, as improvements in functional approximations or abinitiotechniques will eventually render CDFT unnecessary (we hope). However, in the here and now, CDFT has proven to be a valuable tool in theThe 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].Biến đổi Fourier nhanh.
