Calculate the resistivity of Silicon at given that its resistivity at
is
.
The resistivity of intrinsic semiconductors like silicon varies with temperature according to the relation: [ \rho(T_2) = \rho(T_1) , e^{\frac{E_g}{2k} \left( \frac{1}{T_2} - \frac{1}{T_1} \right)} ] where: * (\rho(T_1)) is the resistivity at temperature (T_1) * (E_g) is the energy band gap of silicon ((E_g _____ _________ ________ _____ ________ _________ ______.
