New Method For Determining How 2D Materials Expand (MIT)


A new technical paper titled “A unified approach and descriptor for the thermal expansion of two-dimensional transition metal dichalcogenide monolayers” was published by researchers at MIT and Southern University of Science and Technology (China).

“A new technique that accurately measures how atom-thin materials expand when heated could help engineers develop faster, more powerful electronic devices.,” states this  MIT news article. “Rather than directly measuring how the material expands, they use laser light to track vibrations of the atoms that comprise the material. Taking measurements of one 2D material on three different surfaces, or substrates, allows them to accurately extract its thermal expansion coefficient.”
