The discontinuity in the chemical potential for the change from hole to electron doping is calculated analytically as a function of the on-site Coulomb interaction U, and the charge-transfer energy Δ between the d- and p-orbitals, transfer integrals tpd, tpp, tdd between p-d, p-p and d-d sites respectively. The critical behaviour of the quasiparticle weight is also obtained analytically., Proceedings of the International Conference on Strongly Correlated Electrons with Orbital Degrees of Freedom (ORBITAL2001)}, pages = {217--219}, title = {Critical Behaviour near the Mott Transition in a Two-band Hubbard Model}, volume = {71}, year = {2002} }
