Explain the formation of energy bands in solids on the basis of band theory of Ec+Ev 3 solids. Derive the expression EF = for Fermi level in an 2 + kT In 4 *** mh intrinsic semiconductor. For an intrinsic semiconductor with band gap 0.7 eV, determine the position of the Fermi level at 300 K if the effective mass of hole is six times the effective mass of electron. me
