The rupture of co-valent bonds will occur when the electric field is__________________?

Correct answer: D. More than 105 V/cm

  • A. 100 V/cm
  • B. 6 V/cm
  • C. 1000 V/cm
  • D. More than 105 V/cm

Explanation

A semiconductor's covalent bonds are broken by a very strong electric field, typically exceeding 10^5 V/cm. The smaller listed fields are insufficient for this avalanche-type ionisation process.
