Abstract: We want to answer the question of whether the divergence in the effectivemass in metal-insulator transition MIT in 2DEG is in the same universalityclass as percolation. We use a model to make Percolated state in 2D and thencalculate the effective mass in a super-cell and the Bloch Theorem. It is seenthat the effective mass, m*, scales as m*~P-Pc^a with a=1 and Pc being theclassical percolation threshold.
