Exam Questions Papers

Q1:
  1. Hall coefficient RH is directly proportional to the charge density
  2. RH depends upon type of the semiconductor material (n - type or p - type)
  3. Hall co-efficient RH is directly proportional to hall voltage VH
From the above statements which are the false statements?

A I only

B II only

C III only

D all of the above

ANS:A - I only

where r is charge density and RH = + ve, then the material is p - type = - ve, then the material is n - type RH ∝ VH where VH is Hall voltage.
