Negative-donor centers in two dimensions

A variational calculation of the bound states of negative-donor centers D- in two dimensions is presented; exchange and correlation effects are included using a Chandrasekhar-type trial wave function. At zero magnetic field, a binding energy of 0.45 Ry* is obtained for the singlet ground state, eigh...
