The electrical stability of semiconductor devices over long periods of time is an important attribute in determining the usefulness of devices or new semiconductors compared to conventional devices and silicon, the industry standard semiconductor. Zinc oxide is a relatively new semiconductor material for which the long term stability of the material and devices is currently unknown. In this work, the electrical stability of zinc oxide thin film transistors was measured through electrical stress testing. The temperature sensing properties of a zinc oxide transistor array were also measured.
