Cellular Nonlinear Network with Spin Wave Bus

We propose and analyze a cellular nonlinear network based on semiconductor nano-structure consisting of multiple layers of two semiconductors along with an incorporated ferromagnetic layer - spin wave bus. A bi-stable elementary logic cell of the proposed CNN consisting of two resonant tunneling diodes inductively coupled with the ferromagnetic layer. The local interconnections of nano-cells are achieved via the spin waves propagating in the spin wave bus. The cells are biased by the common column contacts and only the edge cells have individual I/O ports. Using approximate tunneling characteristics and experimentally obtained data for spin wave propagation in CoFe thin film, we simulated the coupling between an individual cell and spin wave bus. The proposed CNN architecture for nano-structures possesses powerful computing potential to be beneficial for many practical applications
