LOGICAL CIRCUIT AND SINGLE ELECTRON SPIN TRANSISTOR

摘要

A single electron spin transistor (100) includes a source (102), a drain (104), an island (101) arranged between the source and the drain with tunnel junctions (103, 105) between the source and the drain, respectively, and a gate (106) capacitively coupled to the island. At least one of the source, the drain and the island includes a ferromagnetic body whose magnetization direction can be changed. A logical circuit wherein such single electron spin transistor is provided and a function is reconfigurable in a nonvolatile manner, and a single electron spin transistor are provided.
