What temperature does p-Ge translates from extrinsic to intrinsic ?

  1. Jul 25, 2013 #1

    I have expermentally measured the resistivity, Hall mobility concentration of a p-type germanium sample at the range of 300K-700K. The task I want to accomplish is, given the fact that I know NA= 4.5E17 and acceptor is boron.

    - How can I calculate the expected transition temperature from extrinsic to intrinsic?
    - How can I assume the expected resistivity, mobility and concentration values so I can compare them with the experimental values? Which scattering mechanisms will dominate?

    Thanks in advance.
