Spin logic via controlled correlation in a topological insulator-nanomagnet hybrid structure

摘要

A magnetic switching device implemented with a majority-gate logic structure is explored as a potential candidate for beyond-CMOS technology. Specifically, a novel switching mechanism is envisioned that relies on the unique magneto-electric properties of a hybrid structure consisting of topological insulator (TI), insulating ferromagnet (FM) and graphene (Gr) in the Bennett clocking operation scheme (Fig. 1A). A circuit layout is proposed and the logic operation demonstrated in a 1-bit adder.
