Shuang Wu, a postdoctoral researcher in Zhu's lab, said the lab's previous work used the stretchable heater for continuously bending a bilayer structure.

"How the interfaces of the bilayer align with each other and through what mechanism they transform into a different configuration is very important," Zhang says.

"It controls the properties of the entire bilayer system which, in turn, affects both its nanoscale and microscopic behavior."

"But what we found, actually, is it has a nucleus -- a localized nanoscale aligned domain -- and this domain grows larger and larger in size. Given the correct conditions, this aligned domain could take over the entire size of the bilayer."

They first encapsulated the twisted bilayer in graphene, essentially building a little reaction chamber around it, to look at the bilayer at atomic resolution as it was heated.
