摘要：Metal-insulator transition in doped semiconductors is investigated in the presence of intense magnetic field. Using Tho mas Fermi screening functio n and a screened coulomb potential in the Hamiltonian, a two parameter variational calculation leads to metall ization. The correlation effect among the electrons is considered through an effective mass threat depends on the spatial separation between impurities.
