MCQ
A semiconductor X is made by doping a germanium crystal with arsenic (Z = 33). A second semiconductor Y is made by doping germanium with indium (Z = 49). The two are joined end to end and connected to a battery as shown. Which of the following statements is correct
  • A
    X is P-type, Y is N-type and the junction is forward biased
  • B
     X is N-type, Y is P-type and the junction is forward biased
  • C
     X is P-type, Y is N-type and the junction is reverse biased
