Q:

The mobility of conduction band electrons is greater than that of holes because

  • 1
    they are light
  • 2
    they collide less often
  • 3
    they have negative charge
  • 4
    they require less energy to move
  • Show Answer
  • Workspace

Answer : 2. "they collide less often"
Explanation :

In a semiconductor the mobility of electrons (referring to 'conduction electrons' or 'free-electrons') is greater than that of a holes (indirectly referring to 'valence electrons') because of different band structure and scattering mechanisms of these two carrier types
