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

Hi,

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?
