Abstract
By making an ovonic threshold switch using a carbon interfacial layer having a thickness of less than or equal to ten percent of the thickness of the associated electrode, cycle endurance may be improved. In some embodiments, a glue layer may be used between the carbon and the chalcogenide of the ovonic threshold switch. The glue layer may be effective to improve adherence between carbon and chalcogenide.
