Q1. In a P-type germanium, ni = 2×10" electrons/m and the density of
boron 4x1023 atoms/m'.
The electrons and holes mobility are (0.4 and 0.2 m2/ V. s) respectively.
What is its conductivity before and after addition of boron atoms?
Note: For after addition of boron atoms you need to compare the
actual and approximate conductivity
