A one-dimensional model study of charge transport in nanodevices is made by comparing multiconfiguration time-dependent Hartree-Fock and frozen-core calculations. The influence of exchange and Coulomb correlations on the tunneling current is determined. We identify the shape of the tunneling barrier and the resonance structure of the nanodevice as the two dominant parameters determining the electron transport. Whereas the barrier shape determines the size of the tunneling current, the resonances determine the structure of the current.
