The interplay between the electron transport in metal-ferroelectric-metal junctions with ultrathin ferroelectric barriers and the polarization state of a barrier is investigated. Using a model which takes into account screening of polarization charges in metallic electrodes and direct quantum tunneling across a ferroelectric barrier, we calculate the change in the tunneling conductance associated with the polarization switching. We find the conductance change of a few orders of magnitude for…

Giant tunnel electroresistance with PbTiO3 ferroelectric tunnel barriers
The persistency of ferroelectricity in ultrathin films allows their use as tunnel barriers. Ferroelectric tunnel junctions are used to explore the tunneling electroresistance effect—a change in the
Tunneling electroresistance in ferroelectric tunnel junctions with a composite barrier
Tunneling electroresistance (TER) effect is the change in the electrical resistance of a ferroelectric tunnel junction (FTJ) associated with polarization reversal in the ferroelectric barrier layer.
Giant piezoelectric resistance in ferroelectric tunnel junctions.
It is found that reversing an applied stress can also change the tunnel barrier sufficiently to produce an effect similar to the giant electro-resistance one due to polarization reversal, which is particularly significant near the stress-dependent paraelectric/ferroelectric phase transition.

The discovered effect is illustrated by the example of a multiferroic tunnel junction in which approximately four orders of changes of the tunneling conductance and several-fold changes ofThe tunneling magnetoresistance (TMR) are observed due to the spin-flip induced nanomechanical stress.

The interfacial magnetoelectric (ME) effect in ferromagnetic-ferroelectric (FM-FE) tunneling junctions was investigated in this work. We found that the tunneling magnetoresistance (TMR) changes with
