The Postma group conducts interdisciplinary research in nanoscience and nanotechnology. We are interested in the properties of materials with intrinsic nanoscale dimensions, such as carbon nanotubes, nanowires, graphene (pictured on the left), and DNA (pictured on the right). Their small dimensions give rise to interesting effects, such as quantum confinement, and we utilize these for novel applications in computation, sensing, and information storage.
We use tools such as Atomic Force Microscopy, Scanning Tunneling Microscopy, electrical transport measurements, and nanolithography as our eyes and ears to tell us what happens at these small scales, and as our hands, to change their behavior to realize new devices.
