| Abstract | In this talk, we discuss the practical examples of the first-principles calculations for three different structures of condensed matters under the frame work of density functional theory (DFT): crystals, nano-cluster, and molecular crystals. For the crystalline structure, we investigate the diffusion of complex impurities in Si crystals [1]. For the nano-cluster, the nano-effects and their promising applications for nano-transistors are studied [2, 3]. Finally, we report the predictions of DFT for the phase transitions of molecular crystal solid Oxygen in compression [4].
