High-Aspect-Ratio Nanogap Electrodes for Averaging Molecular Conductance Measurements
A method of fabricating a pair of closely spaced metal electrodes on the cleaved plane of a GaAs/AlGaAs heterostructure (see image) is presented. These smooth, coplanar electrodes oppose each other over a predetermined distance of a few nanometers, continuously over their entire width of tens of micrometers. This structure may be used for the determination of the average electrical conductance of molecules.
