Intrinsic semiconductor

  • fully insulating @ 0K

  • conductivity from: 1. e- in CB 2. h+ in VB

  • conc. of e- and h+ equal

New cards

What is assumed about temperature dependence of EF for an intrinsic semiconductor?

T independent

as deviation from this very small

3
New cards

How can we find the total conductivity of an intrinsic semiconductor?

σ=ne2τ/m∗\sigma = ne²\tau/m* (data book)

add up conductivity from h & e-
