Calculate the electrical conductivity and resistivity of intrinsic germanium crystal. The mobility of electrons and holes in a sample of intrinsic germanium at room temperature is 0.36 and 0.17 m^2/volt-sec, respectively. The electron and hole densities are equal to 2.5 x 10^19/m^3.

Step 1
It is the inverse of resistivity (\(\rho\)), which measures how strongly a material opposes the flow of electric current. The relationship between conductivity and resistivity is given by: \[ \sigma = \frac{1}{\rho} \] For intrinsic semiconductors like Show more…

The mobility of free electrons and holes in pure germanium are3800 and 1800 cm 2 /V-s respectively. The corresponding values forpure silicon are 1300 and 500 cm 2 /V-s respectively. Determine thevalues of intrinsic conductivity for both. Assume n i = 2.5*10 13 cm -3germanium and n i = 1.5* 10 10 cm -3 for silicon at room temperature.

The intrinsic carrier concentration $$ \text { of a germanium sample } $$ is $2.4 \times 10^{14} / \mathrm{m}^{3}$ at $300 \mathrm{~K}$. Its electron and hole mobilities are $0.39$ and $0.19$ $\mathrm{m}^{2} \mathrm{~V}^{-1} \mathrm{~s}^{-1}$ respectively. Calculate the conductivity of the sample.
Calculate the numbers of electrons and holes per unit volume for a pure germanium crystal at 200,300 , and $400^{\circ} \mathrm{K} .$ (Take $E_{6}=0.70 \mathrm{eV} .$ )
