resistivity of Si wafer at low T

[David Wang]

Hi,

I have a degenerately doped Si wafer (P-type, Boron doped) which has
a resistivity of 0.005 Ohm-cm at room T. Does anyone know what its
resistivity will be when the temperature drops to 0.3 K. Will it behave
like an insulator or a conductor at this low T.

Thanks a lot,

David
