Multilevel nonvolatile transistor memories were fabricated with inserted electret dielectric of star-shaped poly((4-diphenylamino)benzyl methacrylate). The devices could be controllably charged ...

Figure 1: Schematic of the magnon transistor, spatial distribution of the gate magnons and the transistor’s operational principle.

For example, the number of atoms that tunnel from the source to the drain is extremely sensitive to the number of atoms in the gate, meaning atomic transistors could make more effective amplifiers.
