Question

Which of the following conditions form part of Mott’s two-current model? 
 (Tick all that apply, incorrect answers will lower mark)

Answer

When an up-spin electron collides with a down-magnetized atom, it becomes a down-spin electron

Answer

When an up-spin electron collides with a down-magnetized atom, it has an equal chance of being either an up-spin or a down-spin after the collision

Answer

When an up-spin drifts though an up-magnetized material, it has high resistivity

Answer

When an up-spin drifts though a down-magnetized material, it has low resistivity

Answer

When an up-spin drifts though an up-magnetized material, it has low resistivity

Answer

Up-spin electrons drift in the opposite direction to down-spin electrons

Answer

When an up-spin electron collides with a down-magnetized atom, it remains an up-spin electron

Answer

Up-spin electrons have a current path that is in series with the down-spin electrons
