Most electronics are rigid because the materials inside them, such as silicon, are stiff and relatively thick. Electronics that can bend and stretch would be useful for health and medical sensors and for light-sensing devices.

What they work on
- Uncover how capillary forces drive the peeling (delamination) and placement (lamination) of 2D layered materials, using experiments together with computational modeling.
- Determine the energy principles behind van der Waals adhesion, the weak attraction between 2D films and their growth wafers, and relate structure, process and properties across different 2D materials.
- Grow wafer-scale 2D materials by chemical vapor deposition and track the transfer process with in-situ electrical and structural measurements and finite element mechanics simulations.
- Print and stack wafer-scale 2D materials onto target substrates in a controlled way, and test whether their electrical properties stay stable when stretched.
More about the research
Two-dimensional (2D) layered materials are crystals only a few atoms thick, and they can stretch a great deal without breaking, which makes them good candidates. The hard part is manufacturing. These films stick poorly and unpredictably to new surfaces, so it is difficult to move them from the wafer they grow on into a working device without damaging them.
Why it matters
Stretchable electronics could enable wearable healthcare and medical sensors and flexible light-sensing devices. A reliable way to print atomically thin materials at wafer scale could avoid the costly lithographic patterning and etching now needed to make thin, bendable electronics. That could benefit semiconductor manufacturers and the wider electronics industry.
Known grants
From NIH and NSF research grants. Labs often have other funding we can't see.
