Abstract
Provided are high-resolution electrohydrodynamic inkjet (e-jet) printing systems and related methods for printing functional materials on a substrate surface. In an embodiment, a nozzle with an ejection orifice that dispenses a printing fluid faces a surface that is to be printed. The nozzle is electrically connected to a voltage source that applies an electric charge to the fluid in the nozzle to controllably deposit the printing fluid on the surface. In an aspect, a nozzle that dispenses printing fluid has a small ejection orifice, such as an orifice with an area less than 700 μmand is capable of printing nanofeatures or microfeatures. In an embodiment the nozzle is an integrated-electrode nozzle system that is directly connected to an electrode and a counter-electrode. The systems and methods provide printing resolutions that can encompass the sub-micron range.
