The highest photovoltage and operation frequency can be obtained in the IGZO thickness of 300 nm. pH sensitivity is about 65 mV/pH with ac signal frequency at 1 kHz.

These phenomena can be utilized for the synapses in the neural network. It is confirmed that after the learning, the neural network replies the correct answer of AND logic.

We observed that tensile strained TFT with 2 mm bending radius exhibits a positive ΔVTh (V) ~2.3 V shift compared to flat condition TFT (ΔVth (V) ~1.5 V) after 3.6K seconds stress.

In this work, a low-pressure hybrid chemical vapor deposition (LPHCVD) method is applied to fabricate CH3NH3PbI3 perovskite films. The crucial dependence of working pressure on the perovskite formation is revealed. Moreover, the reaction time plays an important role in controlling the quality of the synthesized perovskite film.
