Summary: By employing one-step annealing, we successfully induced ferroelectricity in spray coated ZrO2 with sputtered amorphous InGaZnO (a-IGZO) capping layer, achieving a large memory window of 1.5 V, high I-ON/I-OFF ratio of 1 x 10(7), and steep subthreshold swing (SS) of 0.12 V/decade. The low thermal expansion coefficient of a-IGZO helped induce the polar orthorhombic phase in the underlying ZrO2 layer by providing suitable mechanical stress. This work provides a new approach for inducing ferroelectricity in ZrO2 for high performance ferroelectric thin film transistors.
