Performance of Magnetic Quantum Cellular Automata and Limitations due to Thermal Noise
02 Jun 2011 | Publications | Contributor(s): Ajey Jacob, Dmitri Nikonov
Operation parameters of magnetic quantum cellular automata are evaluated for the purposes of
reliable logic operation. The dynamics if nanomagnets is simulated via Landau-Lifshitz-Gilbert equations with stochastic magnetic field corresponding to thermal fluctuations. It is found that in the …

Taxonomy of spintronics (a zoo of devices)
02 Nov 2006 | Online Presentations | Contributor(s): Dmitri Nikonov, George Bourianoff
The presentation deals with classification of logic devices based on electron spin as a computational variable. Requirements for logic devices are reviewed. Specifically we focus on a) concatenability (output of one device can drive another) and b) the complete set of Boolean operators (NOT, AND, …

Scattering in NEGF: Made simple
09 Nov 2009 | Publications | Contributor(s): Dmitri Nikonov, Himadri Pal, George Bourianoff
Formalism for describing electron-phonon scattering, surface scattering, and spin relaxation is dervied for the Keldysh non-equilibrium Green's functions (NEGF) method. Approximation useful for efficient numerical solution are described. The specific case of the nanoMOS simulator is …
