Investigators at Princeton University Target Nanotechnology
November 1st, 2011
According to the authors of recent research published in the journal Nano Letters, "We studied the local voltage drop in functionalized graphene sheets of sub mu m size under external bias conditions by Kelvin probe force microscopy."
"Using this noninvasive experimental approach, we measured ohmic current-voltage characteristics and an intrinsic conductivity of about 3.7 x 10(5) S/m corresponding to a sheet resistance of 2.7 k Omega/sq under ambient conditions for graphene produced via thermal reduction of graphite oxide," wrote L. Yan and colleagues, Princeton University.
The researchers concluded: "The contact resistivity between functionalized...
