Infrared vision lets researchers see through -- and into -- multiple layers of graphene
Date:11/21/2013

BUFFALO, N.Y. It's not X-ray vision, but you could call it infrared vision.

A University at Buffalo-led research team has developed a technique for "seeing through" a stack of graphene sheets to identify and describe the electronic properties of each individual sheet even when the sheets are covering each other up.

The method involves shooting a beam of infrared light at the stack, and measuring how the light wave's direction of oscillation changes as it bounces off the layers within.

To explain further: When a magnetic field is applied and increased, different types of graphene alter the direction of oscillation, or polarization, in different ways. A graphene layer stacked neatly on top of another will have a different effect on polarization than a graphene layer that is messily stacked.

"By measuring the polarization of reflected light from graphene in a magnetic field and using new analysis techniques, we have developed an ultrasensitive fingerprinting tool that is capable of identifying and characterizing different graphene multilayers," said John Cerne, PhD, UB associate professor of physics, who led the project.

The technique allows the researchers to examine dozens of individual layers within a stack.

Graphene, a nanomaterial that consists of a single layer of carbon atoms, has generated huge interest due to its remarkable fundamental properties and technological applications. It's lightweight but also one of the world's strongest materials. So incredible are its characteristics that it garnered a Nobel Prize in Physics in 2010 for two scientists who pioneered its study.

Cerne's new research looks at graphene's electronic properties, which change as sheets of the material are stacked on top of one another. The findings appeared Nov. 5 in Scientific Reports, an online, open-access journal produced by the publishers of Nature.

Cerne's collaborators included colleagues from
