About the topic

grapheneGraphene is a single-layer material made entirely of carbon that is only one atom thick. While all of us (assuming you’ve used a pencil) have worked with graphite, the multi-layer “parent” of graphene, things get much more interesting when they’re thinned down to a single layer. On paper, graphene has a long list of impressive superlatives: lightest, thinnest, strongest, most impermeable, and most conductive. But where do these properties come from? Do they really pan out when you make graphene in the lab? As graphene makes the jump from theoretical wonder to real-life devices, what types of applications will it most likely be useful for?

In this presentation, I will give an introduction to how scientists make graphene in the lab and study its impressive properties. I’ll also discuss what types of applications graphene could potentially be used for, including batteries, photodetectors, cell phones, and sensors. I’ll also talk about some applications where graphene may not make the cut, despite some early hopes that it would. Never fear, graphene has a plethora of ultra-thin cousins that I’ll briefly discuss that may pick up the slack in those devices. Ultimately, graphene is one example of a broad array of “nanomaterials” that may give us the next generation of faster, smaller, and more efficient devices.

Jeff Blackburn is a senior scientist and group manager at the National Renewable Energy Laboratory (NREL) in Golden, CO. He received his Ph.D in chemistry from the University of Colorado (Boulder) in 2004, and then worked as a postdoctoral researcher at NREL before becoming a staff scientist in 2007.

His research focuses on understanding the fundamental properties of nano-scale materials, including carbon nanotubes, graphene, two-dimensional semiconductors and semiconductor “quantum dots”. His interests span applications that include photovoltaics (solar cells, converting sunlight into electricity), thermoelectric energy harvesting (converting heat to electricity), catalysis (converting sunlight or electrons into fuels), and energy storage (e.g. batteries).
