- Homework Statement
- At room temperature (300 K), the bandgap energy and resistivity of
intrinsic germanium is 0.67 eV and 0.455 ohm/m, respectively.
Determine the resistivity of the intrinsic germanium at 150 °C. Assume
that, at room temperature, the electron and hole mobilities are 0.14 and
0.05, respectively. The bandgap is insensitive to the temperature.
- Relevant Equations
- Shown below.
Hi.
Since,
I can find conductivity by taking the reciprocal of resistivity, in this case, 1/0.455
Hence, I will end up with:
##\frac{1}{0.455}=C(300)^{-3/2}e^{(\frac{-0.67}{2(1.38*10^{-23})(300)})}##
However, my C value seems to be invalid in this case.
May I know what may went wrong here? Thanks
