For semiconductors the resistivity decreases with increasing temperature because increasing temperature increases the probability electrons transition to the conduction band. Here we consider a simplified model for a semiconductors's resistivity. p(T) = Ae-BT The goal is to determine the linear approximation to the resistivity near the temperature To p(T) = Po(1+α(T - To)). Method 1 - Expansion to Linear Order Method 1 expands the resistivity as a series in the small deviation of the temperature AT = T-To and, as you already saw in the expansion method for doing sensitivity analysis, keeps only the term linear in AT. Express as a Function in Delta T-Method 1 0.0/10.0 points (graded) Express the exact resistivity p(T) in the form given below. Enter responses using DeltaT for T-To, T for T, TO for To, A for A, B for B. p(T) = Ae-BT₂ (
