An effective Hamiltonian is developed for the d-d excitation model in the atomic limit. In a weak coupling approximation it is shown that the interaction between itinerant oxygen p holes mediated by virtual d -d excitations of Cu ++ may lead to superconductivity of purely electronic origin.

We present electrical transport and photoluminecence results for high mobility p-type GaAs/(AIGa)As systems. We observe transitions into an insulating state characterized by an activation energy and a threshold electrical field at a (density-dependent) Landau level filling factor. A new line also ap
