試題詳解

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.
