Effect of Premelting on Conductivity of DNA-Lipid Films
Figure 1
Conductivity measurement setup. One-micron-high
tungsten (W) nanoelectrodes with a less
than 5 nm separation were prepared by decomposing Tungsten hexacarbonyl by
focused ion beam [15] on a silicon chip. The silicon chip was then
pressed into the DNA-lipid film surface on
which gold contacts had been predeposited. Below are SEM (left-side
view) and FIB (right-top view) images of the tungsten nanoelectrodes.
