Doctoral candidate publishes on graphene's potential with NSF support
Date:11/18/2010

Since graphene was first isolated in 2004 with the help of Scotch tape, researchers have excitedly turned to the material to discover its potential applications. A single layer of carbon atoms whose applications range from ultrafast electronics to biosensors to flexible displays, graphene is strong, light, transparent, and a conductor of heat and electricity. But what can we do with this new material? As researchers across the globe peel away layer after layer of potential application, Milan Begliarbekov, a doctoral candidate at Stevens Institute of Technology, has found some unique applications for this distinctive material.

Graphene is charged with possibilities for Milan. With the help of a world-class Stevens faculty, support from the National Science Foundation (NSF) Graduate Teaching Fellows in K-12 Education (GK-12) program through the New Jersey Alliance for Engineering Education (NJAEE), and an award from the Air Force Office of Scientific Research (AFOSR), Milan is conducting groundbreaking research of the material. He has already published two papers on graphene in Applied Physics Letters in pursuit of his Ph.D. and has a third paper in the pipeline. Both published articles have also been selected for the Virtual Journal of Nanoscale Science and Technology.

His first published article, "Determination of edge purity in bilayer graphene using -Raman spectroscopy," confirms a technique for differentiating between monolayer and bilayer graphene, and introduces a new method to quantify the composition of graphenes chiral edges through -Raman spectroscopy.

Milan's second article, "Aperiodic conductivity oscillations in quasiballistic graphene heterojunctions," establishes a new signature of Klein tunneling in graphene heterojunctions. The research has applications in nanolectronics such as graphene field effect transistors (GFET), which have been shown to be capable of ultra-high frequency (300 GHz) operation.
