Device physics:  Silver nanoswitch

Ionic conductors have many applications — in sensors, fuel cells and batteries. Are nanoelectronic devices based on ionic conductors now about to replace silicon?

Most electronic appliances are based on digital electronics, which in essence just require a lot of switches working together in an organized fashion. Much research has been aimed at finding a reliable switching mechanism that can beat conventional silicon technology to permit ever smaller and more powerful electronics.
