Abstract
A polarization induced strain coupled two dimensional field effect transistor (PoSt FET) memory cell is disclosed which includes a transistor including a source contact, a drain contact, a gate contact, a back contact, a channel disposed atop the gate contact, wherein the channel and the gate are separated by an electrically insulating material, and a piezoelectric (PE)/ferroelectric(FE) (PE/FE) layer disposed between the gate contact and the back contact and configured to store bit information in form of ferroelectric polarization (P), wherein a ratio of cross-sectional area of the channel to cross-sectional area of the PE/FE layer is between about 0.03 to about 0.07.
