GATE ECE 2014 Set 4 | Question: 9
In the figure, $\text{ln }(\rho _i)$ is plotted as a function of $1/T$, where $\rho_i$ is the intrinsic resistivity of silicon, $T$ is the temperature, and the plot is almost linear. The slope of the line can be used to estimate band gap ... the sum of electron and hole mobility in silicon $(\mu _n + \mu _p)^{-1}$ intrinsic carrier concentration of silicon $(n_i)$
