      Two-nanometer laser synthesized Si-nanoparticles for low power memory applications 

      El-Atab, N.; Okyay, Ali Kemal; Nayfeh, A. (Springer International Publishing, 2016)
      Current flash memory devices are expected to face two major challenges in the near future: density and voltage scaling. The density of the memory is related to the gate length scaling which is constrained by the gate stack, ...
