Polarity change “on-the-fly” and XOR behaviour.
(a) Transfer characteristics obtained for fixed values of the control gate bias and sweeping the program gate voltage. We can see how for VCG = 0 the device shows its OFF-state ambipolar behaviour by conducting both electrons and holes, according to the value of VPG. The inset shows the measurement configuration. (b) 3D view of the device switching properties, highlighting the XOR operation based on the values of the program and control gates. The inset shows the truth table of the pseudo-logic function implemented.
