AD = μ - VT additive relation
BD·μ = kT/q always relation
CD = μ² · VT only relation
DD/μ = kT/q (thermal voltage)
Answer & Solution
Correct answer: D. D/μ = kT/q (thermal voltage)
**Einstein relation:** D = μ·kT/q.
Connects diffusion coefficient and mobility via thermal voltage.
Applies separately to electrons and holes (Streetman Ch.3).
