The biggest drawback of using semiconductor detectors consists of the fact that at room temperature the number of carriers in the conductive band will be observed as \"noise\" in our instrument. The most common solution consists in lowering the temperature of the Ge crystal to 98 Kelvin using liquid nitrogen. Assume the band gap of Ge stays at 0.67 eV both at 98 and 300 K, and you can use the approximation that $F_{FD} \sim e^{-(E-E_{FD})/KT}$. a. Knowing that germanium has 4 valence electrons, 1 mol of germanium weights 73 g and contains $N_{avogadro} = 6.02 \times 10^{23}$ atoms, calculate the number of conductive electrons above the fermi energy at room temperature (300 K) per gram of Ge from the integral of the fermi-dirac probability distribution. b. Using the formula from above calculate the number of conductive electrons per gram of Ge when refrigerated with liquid nitrogen (98 K) 1.0 0.8 0.6 0.4 $KT = \mu/100$ $KT = \mu/10$ $KT = \mu/2$ $KT = \mu$ 0.2 0.0 0 1 2 3 4 5 $\epsilon/\mu$ Frmi-dirac distribution at different temperatures (relative to fermi gap energy of $\mu = E - E_{fd}$)
