*ABSTRACT*

Emerging energy and electronics technologies such as lightweight solar
cells, low power computing devices, and earth-abundant water splitting
could help power the renewable energy transition, but their impact is
limited by their performance and manufacturability. Here we pose that
scalable nanomanufacturing via printing could address these needs by
allowing low-cost integration of high-performance materials over large
areas and in new 3D geometries.

We apply printing to three challenges in scalable fabrication: 1) How to
print high performance ultrathin semiconductors, 2) How to design inks for
printing large area solar cells, and 3) how to print 3D electrodes for
energy devices. We first focus on an emerging class of two-dimensional (2D)
metal oxide semiconductors printed via roll-based Cabrera Mott surface
oxidation of liquid metals. We discuss the engineering of heterostructures
of 2D oxides as degenerate TCOs and as semiconducting channels for
transparent transistors and we examine the impact of quantum confinement on
their optoelectronic properties towards applications in large area
electronics. We next investigate the physics of roll-based flexography of
metal halide perovskite solar cells, showing the fluid mechanics that
enables large-area patterning at state-of-the-art uniformity to enhance
device performance and stability. Finally, we consider fabrication of
3D-printed metal oxide microlattices for gas sensing and electrocatalysis,
showing how graph-theory and additive manufacturing can boost efficiency
and enhance 3D mass-transport.

*BIOGRAPHY*

Prof. William Scheideler graduated summa cum laude from Duke University in
2013 with B.S.E. degrees in Electrical Engineering and in Biomedical
Engineering. He completed his Ph.D. as an NSF Graduate Research Fellow in
Electrical Engineering at the University of California, Berkeley, where his
doctoral thesis explored scalable nanomanufacturing of metal oxide
electronics. He completed his postdoctoral studies in Materials Science and
Engineering at Stanford University, where he studied scalable fabrication
and thermomechanical reliability of perovskite solar cells. Will joined the
faculty of Dartmouth College’s Thayer School of Engineering as an Assistant
Professor in 2019, launching the SENSE (Scalable Energy and Nanomaterial
Electronics) Laboratory. His research interests include 3-D
nanomanufacturing and 2D materials for electronics and energy applications.
In 2023, William was a recipient of the SME’s Delcie Durham Outstanding
Young Manufacturing Engineer Award recognizing his research in advanced
electronics manufacturing.
