Inkjet-patterned titanium oxide memristive junctions connected in series for a threshold indicator
Here memristive metal/oxide/metal junctions were patterned by inkjet printing, and the printed device characteristics were measured to infer ionic and electronic transport parameters such as mobilities and ion distribution.
