Query: Ultra-low-energy non-volatile straintronic computing using single
  multiferroic composites   The primary impediment to continued downscaling of traditional charge-based
electronic devices in accordance with Moore's law is the excessive energy
dissipation that takes place in the device during switching of bits. One very
promising solution is to utilize multiferroic heterostructures, comprised of a
single-domain magnetostrictive nanomagnet strain-coupled to a piezoelectric
layer, in which the magnetization can be switched between its two stable states
while dissipating minuscule amount of energy. However, no efficient and viable
means of computing is proposed so far. Here we show that such single
multiferroic composites can act as universal logic gates for computing
purposes, which we demonstrate by solving the stochastic
Landau-Lifshitz-Gilbert (LLG) equation of magnetization dynamics in the
presence of room-temperature thermal fluctuations. The proposed concept can
overwhelmingly simplify the design of large-scale circuits and portend a highly
dense yet an ultra-low-energy computing paradigm for our future information
processing systems.
