複選題16. Consider a p-n diode. Which of the following statements are correct? (A) Electrons on the n side and holes on the p side will flow towards each other and recombine until all the carriers are neutralized. (B) When the diode is forward biased, both electron current and hole current will flow in the diode contributing to the overall current. (C) When the diode is reverse biased, the current in the diode is essentially negligible if there is any. (D) A good quality diode can be easily formed by mechanically compressing p- and n- type semiconductors into close contact. (E) All of the above.

複選題15. Consider energy bands in a crystal. Which of the following statements are correct? (A) The conduction band of a metal is partially filled by electrons. (B) Existence of energy gap is a manifestation of quantum mechanical phenomenon. (C) Intrinsic semiconductors cannot conduct electricity at all even at high temperatures. (D) Doped semiconductors can conduct electricity primarily with the carriers in the conduction band or holes in the valence band. (E) All of the above. 注

複選題14. You want to calculate electron waves 4(x) in a thin wire (1-dimensional). What if the potential outside the wire were infinite? Which of the following statements are correct in this scenario? (A) The allowed kinetic energies of electrons should be quantized. (B) (x) 0 everywhere000 eV (C) (x) ≈0 everywhere, except for 0<x<L. 이 L (D)y(x) = 0 everywhere, except for 0<x<L (E) Can't tell anything yet. Need to find y(x) first. mathematically V(x) = ∞ for x<0 and x>L V(x) = 0 eV for 0>x<L
