Ferroelectric field effect.
Resistivity versus temperature for the CMO channel with thicknesses (tCMO) of (a) 6 u.c., (b) 10 u.c., (c) 20 u.c. and (d) 40 u.c. The virgin states are shown as red lines (“ON” state), which were switched to “OFF” state (blue lines) with the negative writing voltage (−V) and switched back to “ON” (green lines) with the positive one (+V). Schematics in (a) depict the two states in the device.
