Abstract :
In this paper, we have shown that CNT (carbon nanotubes) electrodes enable control of extremely small, ~10 nm volumes of phase change materials (e.g. GST - Ge2Sb2Te5). Reversible SET and RESET programming currents as low as 1-10 μA can be achieved, two orders of magnitude lower than state-of-the-art PCM devices.
