Multi-stack insulator to minimise threshold voltage drift in ZnO FET sensors operating in ionic solutions
FET biosensors operating in an electrolyte experience a monotonic, temporal and relatively slow change in threshold voltage caused by the hydration of the insulator layer between the electrolyte and the FET's channel. Minimising this temporal change in threshold voltage is critical as, over tim...
