Biography

Josh Goldberger received his B.S. in chemistry from The Ohio State University in 2001. He received his Ph.D. in chemistry from the University of California at Berkeley with Professor Peidong Yang in 2006, as an NSF graduate fellow. He then did his postdoctoral research with Professor Sam Stupp at Northwestern University as part of the Institute for BioNanotechnology in Medicine, as an NIH-NRSA postdoctoral fellow (2007-2010). He has received many awards, including an MRS Graduate Student Finalist Award in 2003, an IUPAC Prize for Young Chemists in 2007, and a Camille Dreyfus Teacher-Scholar Award in 2015. He joined the Ohio State Chemistry Department in August of 2010.

The major focus of our lab is to learn how to design new materials that synergistically unite and organize inorganic and organic components for applications in energy conversion and medicine. Similar to how carbon can be sculpted into low-dimensional allotropes such as fullerenes, nanotubes, and graphene, the major premise of our research program is that the framework connectivity of atoms for any crystalline solid can be constrained along specific axes to produce stable, single atom or polyhedron thick derivatives with much different properties than the original material.

We Finally Know What Graphene Is Good For: Origami

They’ve also started using graphene kirigami to measure electricity from firing neurons. Placing cuts on the graphene gives it better electrical contact with the neuron—but the team still has no idea whether graphene will be better than any other material at conducting impulses from the cells.

In the process of experimenting with graphene’s configurations, McEuen’s team also identified what properties make it possible to do kirigami with graphene—a ratio of its stretchability and foldability. And now that those properties are combined in a rule, it’ll make it a lot easier to find other two-dimensional materials that scientists can cut and manipulate. “They pretty much defined what properties a material needs in order to apply kirigami,” says Joshua Goldberger, a chemist at The Ohio State University who studies 2-D materials.

Beyond Graphene, a Zoo of New 2-D Materials Are Being Created

The other major class of 2-D materials more closely resembles graphene. Silicon, germanium, and tin come from the same chemical family as carbon. But, while graphene is quite content as a perfectly flat 2-D layer, silicene, germanene, and stanene prefer a corrugated, slightly 3-D structure.

This means that they easily make chemical bonds with molecules above or below the 2-D plane, giving chemists a new way to tailor the properties of the sheet.

For instance germanene, like graphene, has no band gap, but by bonding a hydrogen atom to each germanium atom, chemists can create one. And, by using a palette of different chemicals, one single sheet can have splotches of different properties. Joshua Goldberger, a chemist at OSU who co-leads their 2-D efforts with Kawakami, envisions using such patterning to create a chemically defined 2-D electronic circuit.

Li Shi and graduate student Gabriel Coloyan explore germanane, a new material that may be useful for electronic devices or thermoelectric energy conversion devices. In partnership with Josh Goldberger's group at the Ohio State University, Shi's team is exploring the nanoscale characteristics of the material, looking for ways to enhance its thermal and electronic properties.

The Future of Electronics—Now in 2D The Ohio State University

2015-02-14

he future of electronics could lie in a material from its past, as researchers from The Ohio State University work to turn germanium—the material of 1940s transistors—into a potential replacement for silicon.

At the American Association for the Advancement of Science meeting, assistant professor of chemistry Joshua Goldberger reported progress in developing a form of germanium called germanane...

Redesigned Material Could Lead to Lighter, Faster Electronics The Ohio State University

2013-04-10

Joshua Goldberger, assistant professor of chemistry at Ohio State, decided to take a different direction and focus on more traditional materials.

“Most people think of graphene as the electronic material of the future,” Goldberger said. “But silicon and germanium are still the materials of the present. Sixty years’ worth of brainpower has gone into developing techniques to make chips out of them. So we’ve been searching for unique forms of silicon and germanium with advantageous properties, to get the benefits of a new material but with less cost and using existing technology.”...
