When an N-type semiconductor is heated:

Correct answer: D. Number of electrons and holes increases equally

  • A. The number of electrons increases while that of holes decreases
  • B. The number of holes increases while that of electrons decreases
  • C. Number of electrons and holes remains the same
  • D. Number of electrons and holes increases equally

Explanation

Due to bond cleavage, an electron-hole pair is always produced. Heating an N-type semiconductor generates equal numbers of electron-hole pairs due to thermal energy.

About Electronics

A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
