The values of the electron effective mass

in Hg
1-xCd
xTe have been calculated for

= 0.20, 0.30, 0.40. Using the Debye temperature θ
Dfor CdTe, the values of the Hooge parameter for Hg
1-xCd
xTe have been estimated as a function of

and the temperature

. In view of the uncertainty in θ
D, the estimate is probably correct within a factor of 2-3. We have also directly calculated θ
Dfor Hg
1-xCd
xTe and its associated Hooge parameters as a function of

; except for a possible temperature dependence of θ
D, the results should be correct near room temperature.
