Query: Engineering Thermal and Electrical Interface Properties of Phase Change
  Memory with Monolayer MoS2   Phase change memory (PCM) is an emerging data storage technology, however its
programming is thermal in nature and typically not energy-efficient. Here we
reduce the switching power of PCM through the combined approaches of
filamentary contacts and thermal confinement. The filamentary contact is formed
through an oxidized TiN layer on the bottom electrode, and thermal confinement
is achieved using a monolayer semiconductor interface, three-atom thick MoS2.
The former reduces the switching volume of the phase change material and yields
a 70% reduction in reset current versus typical 150 nm diameter mushroom cells.
The enhanced thermal confinement achieved with the ultra-thin (~6 {\AA}) MoS2
yields an additional 30% reduction in switching current and power. We also use
detailed simulations to show that further tailoring the electrical and thermal
interfaces of such PCM cells toward their fundamental limits could lead up to a
six-fold benefit in power efficiency.
