FIG. 1.

Schematic of DPN line writing. (a) A line is generated when ink deposits from a moving tip onto a substrate. (b) Top view of the substrate with the regions of ink diffusion where the (i) inner circle represents the tip footprint which has a constant ink concentration and (ii) outer circle is the edge of the SAM.

FIG. 2.

Lateral force microscopy scan of the lines written at a temperature of and relative humidity of 30%. No line was observed at indicating that the cut-off velocity was exceeded.

Image of FIG. 3.
FIG. 3.

Comparison of model prediction to DPN experiments. (a) Line width vs tip velocity. (b) Total ink flow rate vs tip velocity. Experimental data points in the form are as follows: [0.05 310], [0.1 188], [0.25 120], and [0.5 80]. Tip footprint radius is 15 nm.
