What Has Been Achieved

A new way to control the precise folding geometry of 2D sheets has been conceived and validated by a combination of first principles and empirical modeling.

Importance of Achievement

It is challenging to precisely control fold geometry at the nanoscale. Such folds enable the production of new 3D structures from 2D sheets, with potential for new functionalities. This work shows how a very straightforward and familiar process – doping – can control the geometry of folds.

Unique Features of the MIP That Enabled Project

Close collaborative interactions across different disciplines of theory and simulation.
