SANTA: Self-Aligned Nanotrench Ablation via Joule Heating for Probing Sub-20 nm Devices
Feng Xiong, Sanchit Deshmukh, Sungduk Hong +4
Manipulating materials at the nanometer scale is challenging, particularly if alignment with nanoscale electrodes is desired. Here we describe a lithography-free, self-aligned nano…
Nanoscale Phase Change Memory with Graphene Ribbon Electrodes
Ashkan Behnam, Feng Xiong, Andrea Cappelli +9
Phase change memory (PCM) devices are known to reduce in power consumption as the bit volume and contact area of their electrodes are scaled down. Here, we demonstrate two types of…
Direct observation of nanometer-scale Joule and Peltier effects in phase change memory devices
Kyle L. Grosse, Feng Xiong, Sungduk Hong +2
We measure power dissipation in phase change memory (PCM) devices by scanning Joule ex-pansion microscopy (SJEM) with ~50 nm spatial and 0.2 K temperature resolution. The temperatu…
