PCMs are gaining application in memory devices, where a bit of information is stored by changing the phase of a material region with help of heat, long pulse \u2013 recrystallization, short pulse \u2013 amorphization. We found that interconversion between phases could also be done by application of stress field. Compressive stress converts glass into crystal and tensile stress can convert crystal back into glass. Stress- induced interconversion does not impair the material as much as the heat-induced protocol. Stress conversion can also be faster, which allows to design highly efficient memory devices with high areal density.<\/p>\n<p><a href=\" https:\/\/www.lmp.uni-saarland.de\/index.php\/research-topics\/\">back to overview<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Phase change materials are class of materials, which can remain stable in a crystal or amorphous phase at ambient conditions requiring a significant amount of heat for a phase change.
