Figure S12. The I-V characteristics of VO2memristor at 0 °C and 35 °C. a) I-V characteristics at 35 °C. b)I-V characteristics at 0 °C.
The lowest and the highest temperature that the VO2device can operate are shown in Figure S12. When the temperature is greater than 35 °C, the device has almost no stable threshold switching (TS) characteristics (Figure S12a), so the maximum working temperature of this VO2 device cannot exceed 35 °C. When the temperature is lower than 0 °C (the lowest temperature that the test equipment can be lowered to), the device still has stable TS characteristics (Figure S12b), so the minimum operating temperature of this device is less than 0 °C.
