| Double-Wire Electrodes |
|
In the Double-Wire Electrode probe, two platinum wires are tapered inside a dual-channel nanopipette and kept electrically isolated. They can be used to perform electrical measurements on submicron-scale devices, such as resistance and capacitance measurements. Because the probes use normal-force feedback to stay in contact with the surface, these electrical measurements can be correlated with the surface topography obtained through the simultaneous AFM imaging.
