摘要
Symmetrical effective-medium theory is used to find the conductivity and Hall effect of a two-dimensional binary mixture. Results are given in detail in the limit of low applied magnetic field, when the expressions for the Hall coefficients simplify to linear combinations of the corresponding quantities for the components. The Hall constant of a two-dimensional conductor is found to be insensitive to addition of relatively resistive inclusions until their concentration reaches 0.5, which is the percolation limit if the added component is insulating.
