    • We would like to note that Θ in McMillan theory arises from a phenomenological cutoff, which is of the order of the Debye temperature. A precise match between the two is therefore not expected.

    • Since the loss of screening will affect N (0) at the Fermi level but will have no effect on the carrier density n extracted from the Hall effect, the loss of screening should manifest itself as a deviation from the linear trend in σn versus n at large disorder, which we do not observe in our data.
