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.
TLDR
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.
Ferroelectric tunneling under bias voltages
Theoretical investigations of ferroelectric tunneling in a SrRuO3/BaTiO3/Pt junction were conducted, and critical expressions for the surface charge density in the electrodes and the potential
Tunneling magnetoresistance modulation in a magnetic tunnel junction with a ferroelectric barrier.
TLDR
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.
Magnetoelectric effect in ferromagnetic-ferroelectric tunneling junctions
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
Simulation of multilevel polarization in ferroelectric tunnel junctions
A theoretical model of a ferroelectric tunnel junction with multilevel polarization states is proposed, and the model is capable of achieving multiply (i.e., four or eight) logic states by setting
Tunneling electroresistance effect in ferroelectric tunnel junctions at the nanoscale.
TLDR
The obtained results show a change in resistance by about 2 orders of magnitude upon polarization reversal on a lateral scale of 20 nm at room temperature, promising for employing ferroelectric tunnel junctions in nonvolatile memory and logic devices.
The converse piezoelectric effect on electron tunnelling across a junction with a ferroelectric–ferromagnetic composite barrier
