    • Ref. dealt with the case of a small number of repelling holes in the almost filled Na impurity band of a Si MOSFET. In this case the kinetic energy is frozen and the Coulomb repulsion of holes creates Wigner crystal-like order. For a free electron gas it is known that dμ/dn becomes negative (Ref.) at rs =2.1 while classical formulas for energy and chemical potential become accurate only at large enough rs >10. In the intermediate range 2.1< rs <10 one can use quantum mechanical expressions for the energy of the 2DEG (Refs.), leading to qualitatively similar conclusions
