10. There are three types of cubic unit cells, including simple cubic (SC), face-centered cubic (FCC), and body-centered cubic (BCC). Which of the following is   correct  ? (A) BCC has 4 atoms per unit cell (B) FCC has the largest unit cell (C) The coordination number of SC is 8 (D) FCC is alternatively called hexagonal close-packed structure (E) In BCC, the atomic packing factor is 0.68

11. Which of the following statements is   correct  ? (A) The conductivity of metal raises with the increase of temperature (B) the addition of boron into the silicon forms the n-type semiconductor (C) the decrease of temperature enhances the conductivity of semiconductors (D) because both valence band and conduction band are full, the electrons can not move so that the insulator is not conductive (E) because all the valence electrons of carbon form the covalent bonds, the diamond is not conductive
