    An obvious Vth shift was observed after gate-bias stress and recovered. This metastability was attributed to the interaction between the exposed a-IZO backchannel and oxygen/moisture from the atmosphere, regardless of the polarity of stress voltage. This water/moisture sensitivity characteristic can be used for gas sensor application.
