Threshold conduction in amorphous phase change materials: effects of temperature
J C Martinez, Ronald A Coutu, Turja Nandy +1
We emphasize the role of temperature in explaining the IV ovonic threshold switching curve of amorphous phase change materials. The Poole-Frankel conduction model is supplemented b…

Differences in Sb2Te3 growth by pulsed laser and sputter deposition
Jing Ning, J. C. Martinez, Jamo Momand +9
High quality Van der Waals chalcogenides are important for phase change data storage, thermoelectrics, and spintronics. Using a combination of statistical design of experiments and…

Relation between resistance drift and optical gap in phase change materials
J C Martinez, R E Simpson
The optical contrast in a phase change material is concomitant with its structural transition. We connect these two by first recognizing that Friedel oscillations couple electrons…
